Ag107(d,p)Ag108andAg109(d,p)Ag110Reactions

The level structures of ${}_{}{}^{108}{}_{}{}^{}\mathrm{Ag}$ and ${}_{}{}^{110}{}_{}{}^{}\mathrm{Ag}$ have been investigated via the ($d,p$) stripping reaction on isotopically enriched targets of ${}_{}{}^{107}{}_{}{}^{}\mathrm{Ag}$ and ${}_{}{}^{109}{}_{}{}^{}\mathrm{Ag}$ at an incident deuteron energy of 10.0 MeV. The over-all experimental resolution was approximately 20 keV. Proton groups leading to 57 states in ${}_{}{}^{108}{}_{}{}^{}\mathrm{Ag}$ with excitation energies up to 2.78 MeV and 37 states in ${}_{}{}^{110}{}_{}{}^{}\mathrm{Ag}$ with excitation energies up to 1.66 MeV have been identified. Orbital angular momentum transfer values and spectroscopic factors have been extracted for 19 states in ${}_{}{}^{108}{}_{}{}^{}\mathrm{Ag}$ and for 23 states in ${}_{}{}^{110}{}_{}{}^{}\mathrm{Ag}$ using the zero-range distorted-wave Born approximation including an approximation for the nonlocality of the optical potential and a finite-range correction. In ${}_{}{}^{108}{}_{}{}^{}\mathrm{Ag}$, six $l=0\mathrm{}$, nine $l=2\mathrm{}$, one $l=4\mathrm{}$, one admixture of $l=0\mathrm{}$ and $l=2\mathrm{}$, and two admixtures of $l=2\mathrm{}$ and $l=4\mathrm{}$ are assigned. In ${}_{}{}^{110}{}_{}{}^{}\mathrm{Ag}$, six $l=0\mathrm{}$, $l=2\mathrm{}$, and one admixture of $l=2\mathrm{}$ and $l=0\mathrm{}$ are assigned. It is possible that a small fraction of $l=2\mathrm{}$ transitions in ${}_{}{}^{110}{}_{}{}^{}\mathrm{Ag}$ are masked with $l=4\mathrm{}$ transitions. On this assumption, the effective numbers of neutrons outside the closed $g_{\frac{9}{2}}$ orbital in ${}_{}{}^{108}{}_{}{}^{}\mathrm{Ag}$ and ${}_{}{}^{110}{}_{}{}^{}\mathrm{Ag}$ are consistent with the expected values. The summed strengths of the single-particle orbitals are consistent with those of neighboring isotones.
