摘要：

High-spin states in the doubly-odd Z=77 nucleus Ir-188 were populated in the W-186(Li-7,5n) reaction at 52 MeV. Two nearly degenerate DeltaI=1 sequences with the same parity were established. Both bands have been assigned the pih(9/2)circle timesnui(13/2) 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.
