Lifetime measurements of excited states in neutron-rich 44, 46Ar populated via a multinucleon transfer reaction
Lifetimes of low-lying excited states of the neutron-rich 44, 46Ar nuclei, populated via multinucleon transfer reactions, are measured by means of the differential recoil distance Doppler shift method. The extracted electromagnetic transition probabilities are compared with previous intermediate-energy Coulomb-excitation measurements and with large-scale shell-model calculations. The increase in the deduced B(E2 ; 2+→0+) transition probability from 44Ar to the closed-shell nucleus 46Ar contradicts the earlier results of Coulomb-excitation experiments. Shell-model calculations using different effective interactions agree with the new measured values.
