Coulomb excitation of144,146,148,150Nd

Coulomb excitation of ${}_{60}{}^{144,146,148,16050}{}_{}{}^{}\mathrm{Nd}$ by 10.5 and 11 MeV alpha particles was studied by magnetic analysis of particles scattered into 150°. Values of B(E${2;0}^{+}$→$2^{+}$) for the $2^{+}$ states at 696, 454, 302, and 130 keV are 0.58(1), 0.78(1), 1.390(20), and 2.816(35) $e^2$ ${\mathrm{b}}^2$, respectively. For ${}_{}{}^{148}{}_{}{}^{}$,150Nd, values of B(E${3;0}^{+}$→$3^{\mathrm{-}}$) for $3^{\mathrm{-}}$ states at 999 and 932 keV are 0.40(8) and 0.18(3) $e^2$ ${\mathrm{b}}^3$, respectively. For ${}_{}{}^{148}{}_{}{}^{}$,150Nd the hexadecapole transition matrix elements were deduced to be ${0.36}_{\mathrm{-}12}^{+10\mathrm{}}$ and 0.25(12) e ${\mathrm{b}}^2$, respectively. Our measurements are compared to others and to interacting boson model predictions.
