✦ Synopsis

An improved high-resolution study of the beta decay of 4tTi, producfd in the 4°Ca(3He, 2n) reaction at 40 MeV, has been performed at the Ion Guide Isotope Separator On-Line (IGISOL) facility. The beta-delayed radiation was detected by a low-energy charged-particle detector and a large Ge detector for gamma rays. The experimental beta-decay strength and its distribution, extracted from delayed-proton data, are compared with results of shell-model calculations in the 3 + sdfp space. The lowest j,r = ~ , T = 3 state in 41Sc, the isobaric analogue state of the 41Ti ground state, is estimated to contain 10% isospin impurity. @ 1997 Elsevier Science B.V.
