Abstract

The B(E2;0g.s.+21+) value for 38Ca has been measured via the technique of intermediate energy Coulomb excitation using a beam of radioactive 38Ca nuclei. The present result is used to test isospin purity in the mass 38 system by comparing the isoscalar multipole matrix element M0 extracted from the 0g.s.+21+ transitions in 38Ca and 38Ar to the corresponding matrix element obtained from the T=1 states of the Tz=0 nucleus 38K. A discrepancy between the two values of M0 is found, suggesting that isospin symmetry is broken in A=38 nuclei. Similar discrepancies occur for A=34 and 42. Experiments for addressing these discrepancies are proposed.
