Nuclear structure of Cd112 studied through the Cd111(d⃗,p) reaction

Abstract

The nuclear structure of $^{112}\mathrm{Cd}$ has been investigated with the $^{111}\mathrm{Cd}(\stackrel{P\vec}{d},p)^{112}\mathrm{Cd}$ reaction. Isotopically enriched targets of $^{111}\mathrm{Cd}$ were bombarded with 22 MeV polarized deuterons, and reaction products were analyzed with a magnetic spectrograph. Angular distributions and analyzing powers were determined for 129 states, 49 of which are newly observed, up to approximately 4.2 MeV in excitation energy. The observed angular distributions were compared with distorted wave Born approximation (DWBA) and adiabatic distorted wave approximation (ADWA) calculations to extract the spectroscopic factors. Two-quasineutron configurations involving coupling to the ${s}_{\frac{1}{2}}$ orbital are suggested. The sum of spectroscopic strengths extracted by using the ADWA for the individual $l$ transfers are combined with previous results from the $^{111}\mathrm{Cd}(\stackrel{P\vec}{d},t)$ reaction and show good agreement with the $2j+1$ sum rule, whereas those extracted with the DWBA calculations are significantly less.
