Abstract

Lifetimes of the 2(1)(+) states in Ti-44, Cr-48,Cr-50, and Fe-52 were determined with high accuracy exploiting the recoil distance Doppler-shift method. The reduced E2 transition strengths of Ti-44 and Fe-52 differ considerably from previously known values. A systematic increase in collectivity is found for the N = Z nuclei compared to neighboring isotopes. The B(E2) values along the Ti, Cr, and Fe isotopic chains are compared to shell-model calculations employing established interactions for the 0 f 1p shell, as well as a novel effective shell-model Hamiltonian starting from a realistic nucleon-nucleon potential. The theoretical approaches underestimate the B(E2) values for the lower-mass Ti isotopes. Strong indication is found for particle-hole cross-shell configurations, recently corroborated by similar results for the neighboring isotone Ca-42. (C) 2017 The Author(s).
