Lifetime Measurements In Nd-138

Lifetimes of the 2(1)(+), 4(1)(+), 7(2)(-), 10(2)(+), 12(2)(+), and 14(1)(+) states in Nd-138 populated via the Sb-123(F-19, 4n)Nd-138 fusion-evaporation reaction were measured with the recoil distance Doppler shift technique in combination with the differential decay curve method. The B(E2; 2(1)(+) -> 0(1)(+)) value fit well with the systematic trend in the Nd isotope chain and Grodzins rule, which proved that Nd-138 is a transitional nucleus.
