Abstract

A projectile Coulomb-excitation experiment was performed at the radioactive-ion beam facility HIE-ISOLDE at CERN to obtain E2 and M1 transition matrix elements of 140Nd using the multistep Coulomb-excitation code GOSIA. The absolute M1 strengths, B(M1; 2+2 → 2+1) = 0.033(8) µ2N,B(M1; 2+3 → 2+1) = 0.26+0.11−µ2N, and B(M1; 2+4 → 2+1) < 0.04 µ2N, identify the 2+3 state as the main fragment of the one-quadrupole-phonon proton-neutron mixed-symmetry state of 140Nd. The degree of F-spin mixing in 140Nd was quantified with the determination of the mixing matrix element VF−mix < 7+13−7 keV.
