Lifetime measurements in 129,131Xe

Low-spin states of odd-mass xenon isotopes

“…Here, the odd particle is coupled to a bosonic (IBM) core. In the present work, we report the main conclusions of a systematic IBFM-1 calculation for the light xenon isotopes and also compare the predictions with many recent experimental measurements [14,20,21].…”

“…table 1 and the calculated energy values which are compared with the experimental data[20,21] are given in figures 1a-c for 124−126−128 Xe isotopes. This agreement is good for members of the ground state and the γ-bands.…”

The Structure of 131,133 Xe and the Spin(6) Symmetry

“…1. The experimental data were taken from Rets [26] and [28]- [31]. The agreement between calculation and experimental data is good in 131 Xe.…”

“…This is a special case. Calculations using this special form if transition operator failed to reproduce experimental dataJ 28 ^ We have adopted the most ;eneral form of transition operator. For this purpose, we have done the numerical calculation n PBEM.t 32 !…”

“…Table 1. Comparison of experimental,' [28][29][30][31] ' Spin (6) and IBFMl [15) B(E2)'s(e 2 6 2 )for 131 Xe. In comparison with experiments, the Spin(6) limit where only d3/2 single-particle level is taken into account gives equally good description for the energy spectrum of 131 Xe as the more complicated U(6/20) scheme.…”
