Abstract

Isospin mixing induced by the Coulomb interaction has been studied in the compound nucleus ⁸⁰Zr at T~2 MeV produced in the fusion-evaporation reaction ⁴⁰Ca+⁴⁰Ca at E_beam = 136 MeV. The isospin impurity was measured using the first step of the Giant Dipole Resonance γ decay. The preliminary value of the Coulomb spreading width has been extracted via statistical model analysis of the measured γ spectrum.
