Abstract

The inelastic scattering of 20-MeV vector-polarized deuterons from ${}^{24}{Mg}$ , ${}^{28}{Si}$ , ${}^{32}S$ , and ${}^{54}{Cr}$ provides an experimental determination of sign and magnitude of the quadrupole mass transition amplitudes $〈 {2_{1}}^{+} | | Q^{m} | | {2_{1}}^{+} 〉$ , $〈 {2_{2}}^{+} | | Q^{m} | | {2_{2}}^{+} 〉$ , and $〈 {0_{1}}^{+} | | Q^{m} | | {2_{2}}^{+} 〉〈 {2_{2}}^{+} | | Q^{m} | | {2_{1}}^{+} 〉〈 {2_{1}}^{+} | \times | Q^{m} | | {0_{1}}^{+} 〉$ , which correspond to the static quadrupole moments ${Q_{2}}_{1^{+}}$ and ${Q_{2}}_{2^{+}}$ and the $P_{3}$ interference term in the case of electromagnetic transitions.
