摘要：
The isotope Au-176 has been studied in the complete fusion reaction Ca-40 + Pr-141 -> Au-176 + (5)n at the velocity filter SHIP (GSI, Darmstadt). The complex fine-structure alpha decay of two isomeric states in Au-176 feeding several previously unknown excited states in the daughter nucleus Ir-172 is presented. An alpha-decay branching ratio of b(alpha) = 9.5(11)% was deduced for the high-spin isomer in Ir-172.
