- Abstract
- The structure of the low-lying states with negative parity of /sup 93/Rb
has been studied in the framework of the interacting boson-fermion model (IBFM)
using the even-even neighbour /sup 94/Sr as a core. A good description of
the properties of the levels has been obtained. A sensitive test of the
quality of the theoretical studies is the decay pattern of the second
excited state at 267 keV with a half-life of 2.0(2) ns. The calculations
give t/sub 1/2/=2.26 ns and they predict the existence of a 13 keV
transition into the first excited state, the existence of which has been
confirmed afterwards by experiments. (16 References).
