Alignment processes in 119Cs, 121Cs and 123Cs
1992
Rotational band structures have been observed in the odd-A Cs isotopes 119Cs, 121Cs and 123Cs. The previously known bands have been extended to higher spin values and several new bands have been es ...
Neutron and protonh 11/2 alignment effects in121La
1991
In a γ-spectroscopic study, excited states in the very neutron deficient nucleus121La have been established for the first time. Rotational bands built on the 9/2+[404] and l/2−[550] Nilsson orbitals are observed up to a maximum spin of tentatively 51/2ħ. The experimental results are compared with Total Routhian Surface calculations.
Competing proton and neutron alignments in neutron-deficient Xe-nuclei
1994
Abstract High-spin structures of the neutron-deficient 117,118,120 Xe isotopes have been studied by in-beam γ-ray spectroscopic techniques. The final nuclei have been identified by means of charged-particle detectors. Collective rotational bands based on the neutron d 5 2 , g 7 2 and h 11 2 configurations have been identified in 117 Xe. In the even 118 Xe and 120 Xe nuclei several new side bands were observed and the previously known bands were extended. The present level schemes include two positive-parity bands constructed to high spin in 118 Xe, whereas in 120 Xe three such bands were observed. In order to explain these bands, both proton and neutron ( h 11 2 ) 2 alignments, as well as t…
High-spin states in 121Ba and deformation-dependent alignments
1991
The high-spin structure of 121Ba has been investigated by in-beam gamma-ray spectroscopic techniques. Rotational bands based on the h11/2, g7/2 and tentatively d5/2 quasineutron configurations have ...
Evidence for band termination in118Xe
1991
The yrast band of Xe118 has been extended up to tentatively I-pi = 34+ in a heavy-ion in-beam gamma-spectroscopic study using the NORDBALL detector array. A band crossing is observed at the highest ...
Signature inversion in 120Cs: Evidence for a residual pn interaction
1992
Abstract High-spin states have been observed in the odd-odd isotope 120Cs in 32S-induced reactions. The previously known band is extended to higher spin and several new bands are identified. Band-head configurations have been inferred by comparing the band properties with known bands in the odd nuclei 121Cs and 121Ba. A remarkable signature inversion is observed in the π h 11 2 ⊗ν h 11 2
High spin states of120Ba
1991
The very neutron deficient nucleus120Ba has been investigated in a high-spin γ-spectroscopic study. The yrast band of120Ba is extended up to spin 22ħ and one tentatively assigned negative-parity side band is observed up to spin 15ħ. The experimental results are compared with Total Routhian Surface calculations.
Shape coexistence in 117I
1992
The 117I nucleus has been investigated in a high-spin gamma-spectroscopic study using the NORDBALL detector array. The observed level structures are interpreted as resulting from coexisting collect ...
