Abstract

The Li6 and Li7 bombardment of Ca48 in conjunction with recoil distance measurements has been used to measure the mean lifetimes of excited states in Ti51, Ti52, and V52: in Ti51, 2754-keV level (τ=1.2±0.4 nsec) and 2344-keV level (τ=13.9±2.3 psec); in Ti52, 3027-keV level (τ=36.7±6.3 psec); in V52, 2541-keV level (τ=7.7±0.5 psec). The γ-ray decay schemes and lifetimes are consistent with an interpretation involving yrast states of the (π1f72)n(ν2p32,1f52,2p12)m configuration where n=2 or 3 and m=1 or 2. The experimental level energies and B(E2) values are compared with shell model calculations by Horie and Ogawa.

NUCLEAR REACTIONS Ca48(Li6,p2n) ELi6=26 MeV; Ca48(Li7,p3n), Ca48(Li7,p2n), Ca48(Li7,3n) ELi7=28 MeV; measured γ excitations, recoil distance; deduced T12, B(E2), effective charges, decay scheme in Ti51, Ti52, V52; enriched target, Ge(Li) detectors.
