ReactionAr36(d,p)Ar37

The level structure of ${}_{}{}^{37}{}_{}{}^{}\mathrm{Ar}$ has been investigated via the reaction ${}_{}{}^{36}{}_{}{}^{}\mathrm{Ar}\mathrm{}(d,p)\mathrm{}{}_{}{}^{37}{}_{}{}^{}\mathrm{Ar}$ at an incident deuteron energy of 9.162 MeV and with an over-all energy resolution of approximately 30 keV. A total of 53 states of ${}_{}{}^{37}{}_{}{}^{}\mathrm{Ar}$ with excitation energies up to 9.012 MeV have been observed. The orbital-angular-momentum-transfer values and the spectroscopic factors for 29 of the observed states have been extracted using finite-range distorted-wave Born-approximation calculations corrected for nonlocality of the optical potential. One $l=0\mathrm{}$, two $l=2\mathrm{}$, three $l=3\mathrm{}$, and twenty-three $l=1\mathrm{}$ transfer values have been assigned. Spin assignments have been made on the basis of the conventional shell-model ordering of states, by comparison of the states of ${}_{}{}^{37}{}_{}{}^{}\mathrm{Ar}$ with those of the mirror nucleus ${}_{}{}^{37}{}_{}{}^{}\mathrm{K}$, and on the basis of the Lee-Schiffer effect. The spin, parity, excitation energies, and the spectroscopic factors obtained for the lowest few states in ${}_{}{}^{37}{}_{}{}^{}\mathrm{Ar}$ are in fair agreement with those predicted through recent shell-model calculations.
