用反冲距离多普勒频移技术结合微分衰减曲线法测量了(^{138})Nd2(1^+})、4(1^+})、7(2^-})、10(2^+})、12(2^+})和14(1^+})态的寿命。(B(E_2；2_{1}^{+}右排0_{1}^{+}))值符合Nd同位素链的系统趋势和Grodzins规则，证明了(^{138})Nd是一个过渡核。
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.
