Title: Evolution of the N = 40 neutron subshell in 20 ≤ Z ≤ 30 nuclei within the dispersive optical model

Abstract

The evolution of single-particle neutron spectra in the N = 40 isotones {sup 60}Ca, {sup 62}Ti, {sup 64}Cr, {sup 66}Fe, {sup 68}Ni, and {sup 70}Zn is calculated on the basis of the mean-field model featuring a dispersive optical potential. The results of these calculations agree with the idea that the degree of collectivity becomes higher in the {sup 64}Сr nucleus and that the coupling of single-particle motion to this collectivity becomes stronger, as well as with available experimental data, which are indicative of the closure of the N = 40 subshell in {sup 68}Ni and of the trend toward this closure in {sup 60}Ca.

  • Experimental single-particle proton energies in spherical and nearly spherical 20 ⩽ Z ⩽ 28 medium-mass nuclei and their counterparts evaluated with the aid of data formirror nuclei were analyzed on the basis of the dispersive optical model. The parameters of the dispersive optical potential were extrapolated to the region of unstable nuclei, and the values obtained in this way were then used to predict the single-particle proton energies in the 20 ⩽ N ⩽ 50 nuclei under study. The evolution of the particle-hole energy gap was traced, and features peculiar to single-particle spectra of magic and nonmagic nuclei were revealedmore » by comparing single-particle energies with proton-separation energies.« less
  • Within the method of matching experimental data obtained in the neutron-stripping and neutron-pickup reactions on {sup 40,42,44,46,48}Ca isotopes, the single-particle energies and probabilities that neutron states are filled are obtained for the even-even calcium isotopes. These data are analyzed within the dispersive optical model, and good agreement between the calculated and experimental values of the energies of states is obtained. The dispersive optical potential is extrapolated to the region of the unstable {sup 50,52,54,56}Ca nuclei. The calculated single-particle energies of bound states in these isotopes are compared with the results of the calculations within the multiparticle shell model, the lattermore » predicting a new magic number N=34 for Z=20 nuclei.« less
  • The evolution of neutron single-particle spectra in molybdenum isotopes was calculated on the basis of the dispersive optical model over the region extending from stable isotopes to the neutron drip line. The question of how the dependence of surface absorption on the neutron–proton asymmetry and the weakening of spin–orbit interaction affect the single-particle spectra in question is studied. The results agree with the concept according to which the shell effect becomes weaker near the neutron drip line.
  • The dynamical polarization potential corresponding to simple, physical two-channel model is derived and examined paying particular attention to its analytic properties. This enables us to illustrate explicitly the emergence of the general dispersive and retardation features expected from the imposition of causality. The energy dependence of the potential and the associated nonlocality in time, expressed by its Fourier transform, are explored. A physical interpretation of the time nonlocality in terms of the time delay due to the excitation of the inelastic channel will be given.
