“…In both cases the probability of excitation of the 03 level is very low. The low-lying 0~-levels in the neighbouring Xe and Ba isotopes (132Ba [18], lz~176 [11][12][13]) support the hypothesis of the existence of such 0 + level in 13~ The remarks given above are confirmed, by the results of simple calculations in the frame of the Wilets-Jean model. It appears that the 2~-level can be reproduced at the proper position if two different mass parameters are used, namely Bp~ and B~=BT~ =Bx=B>.=B z and if B~p is taken about twice as large as B~.…”

The ~-radiation associated with the fl+ decay of ~3~ to levels in 13~ is studied. The level scheme is established on the basis of the Y-7 coincidence measurements emploing two Ge(Li) detectors. The available experimental data are compared to collective model calculations with V-soft P.E.S. and v-dependent inertial functions. To reproduce levels energy Bo~ value twice as large as other mass parameters is needed. Radioactivity: ~3~ [from ~3~Ep=10MeV]; measured E~, 17, ),y-coin. 13OBa deduced levels, J, re, log ft. Enriched target, Ge(Li) detectors.

“…This model with y-independent PES was recently successfully used to describe the structure of several neutron deficient nuclei (namely 134Ba [8], 124't26Xe [11], 128'13~ [12]) from the Ba, Xe region. However, the use of such a simple potential in the case of t3~…”

The unpaired particle in an odd-mass transitional nucleus exerts forces on the rest of the system leading to an effective shape which is in general dependent on the j-orbital occupied by the extra particle. To account for this polarization effect we propose to modify the collective matrix elements by a phenomenological polarization factor. This enables us to describe also such band structures by the core-particle coupling model for which the common coupling rules seem to fail. Selecting a typical case the model is applied to 123I in order to demonstrate the important role of the polarization. The calculation reproduces fairly well all band structures including their M 1 and E2 decay properties.
