Abstract

Isospin mixing induced by Coulomb interaction has been measured in the compound nucleus 80Zr* with Z = N = 40 at T ~ 2 MeV produced in a fusion-evaporation reaction. The observable sensitive to the isospin purity of the compound nucleus is the giant dipole resonance γ decay. The Coulomb spreading width of the I = I0 + 1 state and the degree of isospin mixing of the compound nucleus has been obtained via statistical model analysis of the measured γ spectrum.
