Neutron-Hole-State Structure inN=81Nuclei. II.Ce140andBa138(p,d)

In continuation of our program of neutron-hole-state studies in $N=81\mathrm{}$ nuclei, angular distributions of deuterons from ($p,d$) reactions (energy resolution ∼35 keV) on ${}_{}{}^{140}{}_{}{}^{}\mathrm{Ce}$ and ${}_{}{}^{138}{}_{}{}^{}\mathrm{Ba}$ at $E_p=35\mathrm{}$ MeV have been measured and compared with distorted-wave Born-approximation calculations including finite-range and nonlocality corrections. These calculations yield acceptable spectroscopic factors and are in fair agreement with the shapes of the experimental angular distributions. The neutron-single-hole energies have been determined. These energies (in MeV) are $d_{\frac{3}{2}}$, 0.0; $s_{\frac{1}{2}}$, 0.33; $h_{\frac{11}{2}}$, 1.07; $d_{\frac{5}{2}}$, 1.72; and $g_{\frac{7}{2}}$, 2.90 for ${}_{}{}^{139}{}_{}{}^{}\mathrm{Ce}$; and $d_{\frac{3}{2}}$, 0.0; $s_{\frac{1}{2}}$, 0.54; $h_{\frac{11}{2}}$, 1.07; $d_{\frac{5}{2}}$, 1.71; and $g_{\frac{7}{2}}$, 2.93 for ${}_{}{}^{137}{}_{}{}^{}\mathrm{Ba}$.
