Proton transfer reactions on Sr isotopes

We have investigated the proton transfer reactions ${}_{}{}^{86}{}_{}{}^{}\mathrm{Sr}\mathrm{}(d,n)\mathrm{}{}_{}{}^{87}{}_{}{}^{}\mathrm{Y}$, ${}_{}{}^{87}{}_{}{}^{}\mathrm{Sr}\mathrm{}(d,n)\mathrm{}{}_{}{}^{88}{}_{}{}^{}\mathrm{Y}$, and ${}_{}{}^{88}{}_{}{}^{}\mathrm{Sr}\mathrm{}(d,n)\mathrm{}{}_{}{}^{89}{}_{}{}^{}\mathrm{Y}$ at 12 MeV incident deuteron energy. Spectroscopic factors are extracted from a distorted wave Born approximation analysis and compared to the spectroscopic factors extracted from the analogous (${}_{}{}^3{}_{}{}^{}\mathrm{He},d$) reactions. A comparison is also made of the ($d,n$) and ($d,{}_{}{}^3{}_{}{}^{}\mathrm{He}$) reactions to determine fractional emptiness and occupation probability of shell model orbitals. Additionally, ground state proton configurations of ${}_{}{}^{86}{}_{}{}^{}\mathrm{Sr}$ and ${}_{}{}^{88}{}_{}{}^{}\mathrm{Sr}$ are determined and the $T_{<}$ states of ${}_{}{}^{89}{}_{}{}^{}\mathrm{Y}$ are studied.
