摘要/描述

By measuring positrons and b-delayed g-rays emitted from mass-separated sources, the decay of 56Cu 4q,T sy1,Ts1. z to states in the doubly-magic nucleus 56Ni was studied for the first time. The half-life of 56Cu was measured to be 78 15. ms, and four b-delayed g-rays were assigned to its decay. The resulting experimental data on Fermi and Gamow-Teller strength are compared with shell-model predictions. q1998 Elsevier Science B.V. All rights reserved.
