Abstract:

The lifetime of the first 2+ state in the nucleus 124Ba has been measured by γ-γ coincidence recoil-distance Doppler shift method. The 109Ag(19F, 4n)124Ba reaction at a beam energy of 75 MeV was employed to populate excited states in 124Ba. The mean lifetime was determined to be 275(12) ps using the differential decay curve method. The value of B(E2;01+→ 21+) for 124Ba deduced from the lifetime is in reasonable agreement with the prediction of the proton-neutron interacting boson model(IBM-2) without Pauli blocking effect.
