Abstract

A careful measurement of the lifetime of the first 2T=1 + state in 42Sc has allowed an accurate experimental test of isospin purity in the A=42 isobaric analogs by using the isospin formalism. A lifetime of 69 (18) fs has been determined, giving an isoscalar matrix element of 6.8 (8) W.u. Previous measurements of the lifetimes in the mirror nuclei 42Ca and 42Ti provided an isoscalar matrix element of 7.1 (5) W.u. which is very close to the presently measured value for 42Sc.
