Description

High-spin states in the doubly-odd Z=77 nucleus 188Ir were populated in the 186W(7Li,5n) reaction at 52 MeV. Two nearly degenerate ΔI=1 sequences with the same parity were established. Both bands have been assigned the πh9/2xνi13/2 configuration, based on the systematic behavior of these excitations in the Ir nuclei and on the measured values for the B(M1)/B(E2) ratios, and they are suggested as candidates for a chiral doublet
