Abstract
Lifetimes of the 2\(_1^{+}\), 4\(_1^{+}\), 7\(_2^{-}\), 10\(_2^{+}\), 12\(_2^{+}\), and 14\(_1^{+}\) states in \(^{138}\)Nd populated via the \(^{123}\)Sb(\(^{19}\)F, 4n)\(^{138}\)Nd fusion–evaporation reaction were measured with the recoil distance Doppler shift technique in combination with the differential decay curve method. The \(B(E2; 2_{1}^{+} \rightarrow 0_{1}^{+})\) value fit well with the systematic trend in the Nd isotope chain and Grodzins rule, which proved that \(^{138}\)Nd is a transitional nucleus.
