ow-lying states of the N=50 nucleus 87Rb have been investigated
in the (alpha, alpha') reaction measuring gamma gamma- and delayed gamma-rf-coincidences.
A half-life of T1/2=6(1) ns was obtained for the level at 1578.1
keV. This experimental result confirms the 9/2+ assignement
and the proton 1g9/2 single-particle character of this state.
Experimental M2 transition strengths in 85,87Rb are compared
with predictions of the shell model and the particle-core coupling mwodel.
