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 ...

Decay properties of very-high-spin states in transitional Er nuclei aroundA=154

1986

Theγ ray continuum structures of the transitional Er isotopes withA∼154 are studied using the reaction74Ge(84Kr,xn)158−xEr atElab=340 MeV. The measurements include energy spectra, total energies, multiplicities, angular distributions and lifetimes using the DSAM method. The analysis of data confirms the previously observed two-bump structure of the continuum radiation. A meticulous subtraction of discrete contributions proves the persistence of the low-energy bump even at high spins, i.e.I>40ħ. The angular-distribution measurements assign predominant dipole structure to the bump atEγ=0.65 MeV, whereas the bump atEγ=1.3 MeV is of almost pure quadrupole character at high spins. The lifetime m…

Study of high spins in $^{173}$Os

1991

High-spin states in 173Os have been studied by γγ-coincidence measurements following the 146Nd(32S, 5n)173Os reaction. Additional information has also been extracted from the reaction 144Sm(32S, 2pn)173Os. Four main sequencies have been identified as the two signature branches of the bands built on the [642]52+ and [523]52− Nilsson states. The band features have been analysed within the framework of the cranked shell model. The positive-parity band provides evidence for a v(i132)2 crossing at low frequency and a π(h112)2 and/or π(h92)2 cross In the negative-parity band the upbend starts at relatively low frequency indicating, presumably, an early v(i132)2 alignment. There is evidence for an…

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
