Abstract

We have measured a mean life of 392 12 psec for the 4.49-MeV (5-) state of Ca40, corresponding to an E2 transition strength of 1.04 0.03 Weisskopf units which is considerably stronger than that predicted by a one-particle, one-hole description of the states. However, this E2 decay rate and those of eight other E2 transitions between odd-parity states can be understood when the states are described as admixtures of deformed and spherical wave functions.
