Lifetime measurements in neutron-rich 63,65Co isotopes using the AGATA demonstrator

Lifetimes of the low-lying (11/2−) states in 63,65Co have been measured employing the recoil distance doppler shift method (RDDS) with the AGATA γ -ray array and the PRISMA mass spectrometer. These nuclei were populated via a multinucleon transfer reaction by bombarding a 238U target with a beam of...

Zusammenfassung:Lifetimes of the low-lying (11/2−) states in 63,65Co have been measured employing the recoil distance doppler shift method (RDDS) with the AGATA γ -ray array and the PRISMA mass spectrometer. These nuclei were populated via a multinucleon transfer reaction by bombarding a 238U target with a beam of 64Ni. The experimental B(E2) reduced transition probabilities for 63,65Co are well reproduced by large-scale shell-model calculations that predict a constant trend of the B(E2) values up to the N = 40 67Co isotope.
