Nuclear Structure and Reaction

Abstract

Low-lying states of theN=50 nucleus87Rb have been investigated in the (α, α') reaction measuringγγ- and delayedγ-rf-coincidences. A half-life ofT1/2=6(1) ns was obtained for the level at 1578.1 keV. This experimental result confirms the 9/2+ assignment and the proton 1g9/2 single-particle character of this state. Experimental M2 transition strengths in85,87Rb are compared with predictions of the shell model and the particle-core coupling model.
