“…For V 47 they agree with Pennsylvania, 8 but not with MIT 5 ; for V 49 they agree with Heidelberg 10 but not with Pennsylvania, 9 and for V 61 and Mn 53 they agree with MIT. 6 The MIT spectroscopic strengths for V 47 are smaller than ours and so are Pennsylvania's for V 49 . In both cases, the difference can be attributed to the choice of the normalization constants which differ by a factor of 1.7.…”

The Ti 46 -48 ' 50 (He 3 , d)V 47 » 49 » 51 and Cr 50 » 52 » 54 (He 3 , flMn 51 -63 ' 68 reactions are studied with high resolution at 10-and 9.5-MeV incident energies, respectively. The / values and spectroscopic factors are extracted by means of the distorted-wave Born-approximation calculations. A systematic study of the pm centroid energies, of the dzn and sm proton hole states, and of the splitting of the /> 3 /2 spectroscopic strength is presented. These quantities, and also the individual energy spectra, are compared with the expectations of the shell model and the Coriolis strong-coupling model. It is concluded that the shell model adequately describes these nuclei, while the Coriolis strong-coupling model fails to explain the observed splitting of the pzn spectroscopic strength. 1 The/n dependence of the angular distributions for certain (d, p) reactions is calculated from the weakly bound projectile (WBP) model of Pearson and Coz. Agreement is found with the observed j n dependence. It is suggested that the model can be used for extracting the value of j n from accurately measured angular distributions.

“…Strictly, of course, effects due to proton scattering also appear in the "unscattered" amplitude through the neutron capturing interaction (4). The wave function « 0 + (k W ', r n) for the incident neutron satisfies lE B -Tn-Vo V t~-V(tn, kpO>o + (k n ,, f n ) =0, (6) where EB is the energy of the neutron in its final bound state and T n is its kinetic energy operator. Because of the interaction (4), UQ + represents a solution for a nonspherical potential and is thus difficult to compute.…”
