The ${}_{}{}^{87}{}_{}{}^{}\mathrm{Sr}(d, {}_{}{}^3{}_{}{}^{}\mathrm{He}){}_{}{}^{86}{}_{}{}^{}\mathrm{Rb}$ reaction was studied at a bombarding energy of 28 MeV. All known low-lying negative-parity states were observed; positive-parity states were either weak or absent. A new negative-parity state is suggested near 1.03 MeV. Distorted-wave calculations were made in order to extract spectroscopic factors. Much mixing of $l=1\mathrm{}$ and $l=3\mathrm{}$ transfers is observed. Detailed comparisons are made with wave functions proposed by Kolata et al. Somewhat larger configuration mixing is found, in keeping with known effects of $g_{\frac{9}{2}}$ neutron holes on $p_{\frac{3}{2}}$ and $f_{\frac{5}{2}}$ protons.
