Three rotational bands in 108Sn have been investigated to high frequency via the 54Fe(58Ni,4p) reaction at 243 MeV. One of these bands is observed to undergo a band crossing at high spin. All three bands show a large decrease in their dynamic moments of inertia, to approximately one third of the rigid body value, as the rotational frequency approaches 1 MeV/. The structures of these bands are thou
Precise level lifetimes have been measured for various superdeformed bands in 148,149Gd and 152Dy with the Doppler-shift attenuation method. From the derived quadrupole moments, Q0, we find large differences in deformation between the yrast bands and some excited bands in the gadolinium isotopes. Moreover, two of the excited Gd bands and the 152Dy yrast band, which have identical moments of inerti
The Nordic states have played a central role in the production of knowledge within the Women, Peace and Security (WPS) agenda. Through a strong research tradition in peace and conflict studies, extensive policy development, and significant international engagement, the Nordic region has contributed to both the theoretical and practical advancement of the agenda. In this article, we examine the WPS
The non-collective and collective high-spin configurations in selected A ~ 90 (Z = 42-45, N = 46-49) nuclei are analysed within the configuration-dependent shell-correction approach using the cranked Nilsson potential. With this method, various high-spin features of nuclei, such as shape coexistence, shape changes, band termination and superdeformation are studied along the yrast line. We concentr
Six rotational bands built on superdeformed intrinsic configurations have been observed in the 149Gd nucleus with the Eurogam spectrometer. Orbital configuration assignments have been suggested on the basis of their effective alignments calculated with the Nilsson-Strutinsky cranking model. Most of the excited bands have identical partners in neighboring nuclei including one case differing by four
The non-collective and collective high-spin configurations in selected A ∼ 90 (Z = 42-45, N = 46-49) nuclei are analysed within the configuration-dependent shell-correction approach using the cranked Nilsson potential. With this method, various high-spin features, such as shape coexistence, shape changes, band termination and superdeformation are studied along the yrast line. We concentrate on the
The low-spin features of odd-mass nuclei in the Z∼62, N∼90 region, for which stable octupole deformations has been previously suggested, are studied without introducing the static intrinsic reflection asymmetry (SIRA). Calculations using a Woods-Saxon potential and taking into account the Coriolis mixing show that most properties can be described in this approximation. Furthermore, the calculated
High spin states in I113 were studied with the Ni58(58Ni, 3pγ) reaction at 240 MeV, using the eurogam array in Daresbury, United Kingdom, with 45 Ge detectors. A total of five deformed intruder bands extending to spins I ranging from (73/2-89/2)Latin small letter h with stroke have been identified, all of which reach frequencies Latin small letter h with strokeω>1.0 MeV and excitation energies ∼25
One of the most interesting features of rotating nuclei is the possibility to study how specific configurations, which show up as collective rotational bands at intermediate spin values, gradually lose their collectivity and terminate in a non-collective state at the maximal spin which can be built within the configuration. The best example of such configurations known at present (in the neutron-d
Rotational cascades observed in neutron-deficient nuclei with Z51 are described as the first examples of smoothly terminating bands in heavy nuclei, since they show a continuous transition from high collectivity to a noncollective state. Excellent agreement between experiment and calculations in the Nilsson-Strutinsky cranking model is obtained for the 51109Sb58 nucleus.
What is the role of deictic gestures in expressing affective valence, and can such gestures serve as an indicator of awareness in choice making? To examine this, we analyzed participants’ deictic gestures toward preferred and non-preferred picture alternatives in an experimental choice justification task. The task involved manipulation: in some trials, participants were presented with the rejected
Based on data obtained with the Eurogam spectrometer, a systematic investigation of superdeformed bands built on single neutron excitations across the N = 86 shell gap has been carried out for gadolinium, terbium, and dysprosium isotopes with 85 ≤ N ≤ 87. In each nucleus, pairs of bands corresponding to degenerate signature partners have been observed. The effective alignment is constant and close
Three rotational bands have been discovered in the nucleus Sb109 that extend in angular momentum to 81/2Latin small letter h with stroke. The rotational frequency at the highest spins reaches Latin small letter h with strokeω1.4 MeV, the highest frequency so far observed in a heavy nucleus. With increasing frequency the collective moments of inertia of all three bands smoothly diminish to unexpect
The competition between collective rotation and single-particle behaviour at high spin in 158Er has been investigated with the Eurogam spectrometer. Band terminating states have been observed in three structures at Iπ = 46+, 48- and 49- and specific single-particle configurations are assigned by comparison with cranked Nilsson-Strutinsky calculations. These special states are found to be related b
Six new rotational bands have been established in I115 at high spin using the near symmetric Ni60(58Ni,3p) reaction at 250 MeV. Several of the bands are observed to frequencies beyond Latin small letter h with stroke=1.0 MeV (spin approaching 50Latin small letter h with stroke). All the bands show a characteristic drop off in their dynamic moments of inertia with increasing spin. The low values at
Previously proposed high spin states in Na22,23 are compared with calculations from the cranked Nilsson model including Strutinsky renormalization. High K rotational isomers are proposed for Iπ=6- in Na22 and 11/2+, 13/2+, and possibly 15/2+ in Na23. The positive parity yrast sequences in these two nuclei are analyzed in terms of the change from collective to single particle behavior at I=9 (22Na)
An enhanced-deformation (ED) rotational band with unusual characteristics has been discovered in the odd-Z nucleus Pr131. The dynamical moment of inertia J(2)=(50-60)Latin small letter h with stroke2 MeV-1 and the extracted quadrupole moment Q0 = 5.5 ± 0.8 eb (β2=0.32±0.05) are comparable with other ED bands (sometimes called ''superdeformed'') in the mass A∼130 region. The two signature partners
Two weakly populated rotational bands have been established in Sn106 from the Fe54 (58Ni,2p) reaction at 243 MeV. One of the bands shows evidence of termination. The result is consistent with cranked Nilsson model calculations, which predict band terminations with a smooth and gradual shape change from a prolate collective to an oblate noncollective structure.
Relative properties of superdeformed bands are exploited in terms of the [effective] alignment of the valence particles. Observed and calculated quantities are compared leading to assignments of configurations and relative spins. Within one formalism, both typical differences between some bands and identity of other bands are understood.
