“…The experimental value differs depending on the optical-model parameters used to analyse the 50 Ti(d, p) experiment: 0.54 and 0.37 with different parameters. 19) The spectroscopic factor obtained by the present calculation is 0.47 which is in good agreement with the experiment. This quantity reflects a strong mixing between one-nucleon excitation from the sd to pf shell (33%) and the excitation from the pf to sdg shell (67%).…”

“…However, we find that the 9/2 + 1 state of 51 Ti provides an important clue to determine the location of the 0g 9/2 orbit because it has a large 0g 9/2 spectroscopic factor for the 50 Ti(d, p) reaction. 19) We thus determine the singleparticle energy of 0g 9/2 so that this energy level can be exactly reproduced. On the other hand, since the remaining sdg orbits are of less importance, it is reasonable to determine their single-particle energies schematically: the energy splitting of the neutron sdg orbits, which are defined by the effective single-particle energies on top of 48 Ca, is to follow that of the v ls l · s spin-orbit potential, where v ls = −1.8 MeV.…”

The evolution of the shell structure around N = 28 is described by the shell-model calculation using an effective interaction based on the monopole-based universal interaction. Performing shell-model calculations, we successfully describe the configuration mixing and deformation from which the shell evolution in this region is well clarified. The reduction of the proton spin-orbit splitting from N = 20 to 28 is dominated by the tensor force and is quantitatively reproduced well in terms of the distribution of the spectroscopic factors. This reduction also brings about a large oblate deformation in 42 Si. The location of the neutron 0g 9/2 orbit in Ca isotopes is identified by their 3 − 1 states. §1. IntroductionThe change of the shell structure, often referred to as the shell evolution, has recently attracted much theoretical and experimental interest in the physics of exotic nuclei. 1) The understanding of the shell evolution has been greatly advanced in terms of the nuclear force since it was pointed out that the tensor force, accounting for the evolution of the energy levels in the Sb isotope chain, 2) causes the change of the spin-orbit splitting.3) The shell-evolution picture due to the nuclear force becomes more complete when the central force is included. It has been found 4) that a simple Gaussian central force has successfully reproduced the tensor-subtracted monopole interaction of empirically fitted interactions. This finding has lead to the monopolebased universal interaction (V MU ) 4) which consists of the one-range Gaussian central force and the π + ρ meson exchange tensor force for the purpose of giving a simple and universal monopole interaction, or shell evolution.While V MU seems to be promising as far as the single-particle energy is concerned, the validity of V MU as the effective interaction, which produces configuration mixing and deformation, has not been clarified. In the present paper, we aim at demonstrating that V MU is quite effective as the shell-model interaction as exemplified by the sd-pf -and sd-pf -sdg-shell regions. We focus on the states which are

“…In these calculations, (i) naturaland unnatural-parity states are calculated from the full 0hω and 1hω configurations, (ii) the effective interaction is constructed by analogy to the SDPF-MU interaction: USD (sd) + GXPF1B(pf ) + (refined) V MU (for the remaining two-body matrix elements) [28], and (iii) the single-particle energy of the g 9/2 orbital was chosen to reproduce the excitation energy of the 51 Ti(9/2 + 1 ) state, for which C 2 S was measured to be reasonably large [29]. The calculated C 2 S of 0.47 agrees well with the experimental values of 0.54 or 0.37 for 51 Ti [29]. The singleparticle energies (SPEs) of the other sdg orbitals follow schematic spin-orbit splitting, not affecting C 2 S(g 9/2 ).…”

The Ti 50 (He 3 ,d) V 51 reaction has been studied at 16.4-MeV incident energy with an over-all energy resolution of 20 keV full width at half maximum (fwhm). 57 levels in V 51 were identified up to 9.5-MeV excitation, and corresponding deuteron angular distributions were recorded in the angular interval 7° to 50°, Spectroscopic information has been extracted for 27 of the strongest or most well-isolated transitions by means of a distorted-wave analysis of the differential cross sections. The results are compared with nuclear-structure model predictions.
