R. Krucken et al., Lifetimes in neutron-rich fission fragments using the differential recoil distance method - art. no. 017305, PHYS REV C, 6401(1), 2001, pp. 7305
Lifetimes in the neutron-rich nuclei Mo-104, Ru-110, and Ba-144 were measur
ed using the differential recoil distance method. The experiment was perfor
med with a Cf-252 fission source inside the New Yale Plunger Device. gamma
rays were detected by the SPEctrometer for Experiments with Doppler shirts
at Yale (SPEEDY) while fission fragments with the appropriate kinematics we
re detected by an array of photocells.
