[en] It is shown that the rotating mean field of triaxial nuclei can break the chiral symmetry. Two nearly degenerate ΔI=1 rotational bands originate from the left-handed and right-handed solutions. (c) 2000 The American Physical Society

[en] Further analysis of previously published data on sup(168)Er, together with results of new measurements of selected portions of the neutron capture γ-ray spectrum, has resulted in the construction of an improved level spectrum for this nucleus. Altogether 127 excited levels have now been established and grouped into 36 rotational bands. Some remarks on their interpretation are advanced

[en] The present talk has three parts: first, a discussion of our current ideas about the physics of very high spin states; second some comments about noncollective behaviour up to the highest spins where it is known, approx. 40 h/2π; and finally, a presentation of the newest method for studying collective behavior up to spins of 60-70 h/2π. The intention is that the overview presented in the first part will be sufficiently broad to indicate the relationship of the noncollective and collective behavior discussed in the other parts, and to provide some understanding of the compromise in behavior that seems to occur at the very highest spins.

[en] Isobaric analogues of three states in "1"0Be forming a rotational band with high moment of inertia are expected in "1"0B and "1"0C. This article reports a measurement of excitation spectrum in "1"0B obtained through "1"1B("3He,α)"1"0B reaction. A T = 1 state is found on 11.3 MeV excitation energy. It is a possible candidate for the 4"+ state of the analogue rotation band. (author)

[en] The nucleus ¹¹⁶Te has been studied using the reaction ⁶⁴Ni(⁵⁶Fe,2p2n) at a beam energy of 236 MeV. Both self-supporting and backed target experiments were performed at the (EI) GAMMASPHERE array equipped with 36 suppressed Ge detectors. A total of 2 G and 0.1G three- or higher fold events were collected respectively, with a yield of ∼15% in the 2p2n channel. This experiment endeavored to search in ¹¹⁶Te for novel intruder rotational bands involving proton particle-hole excitations across the Z = 50 closed shell gap. These intruder bands have the unique characteristic of gradually decreasing dynamic moments of inertia with increasing spin to unusually low values, a behavior that has been interpreted as evidence for open-quotes softclose quotes band termination in which the nuclear shape gradually evolves from collective prolate to noncollective oblate. Two such intruder bands, reaching spins of 26ℎ and 40ℎ, have been extracted from these data, both of which are connected to known low-lying states in ¹¹⁶Te
