Coulomb Excitation ofSi28Projectiles

Abstract

The static quadrupole moments of the first excited $J^{\pi }=2^{+}$ states in ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$ and ${}_{}{}^{62}{}_{}{}^{}\mathrm{Ni}$ were measured to be $Q=0.17\mathrm{}\pm 0.05$ b and $Q=0.08\mathrm{}\pm 0.12$ b, respectively, using the reorientation effect in Coulomb excitation with 70-MeV ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$ projectiles incident on a ${}_{}{}^{62}{}_{}{}^{}\mathrm{Ni}$ target.
