Parameters of the proton shell structure of the 40,42,44,46,48Ca nuclei and their analysis within the dispersive optical model

Nucleon–nucleus real potential of Woods–Saxon shape between 60 and 60 MeV for the 40 A 208 nuclei

“…The authors wish to thank Dr. S.Typel for his providing them with the numerical results of RMFT calculations of the single particle energies of nucleon bound states in various nuclei. (Bespalova et al, 2001b;Bespalova et al, 2002) were obtained by joint evaluating the stripping and pickup reaction data. The values in parenthesis are the errors due to the uncertainty of the final-nucleus state spins; a 10% experimental error should be added.…”

“…The values in parenthesis are the errors due to the uncertainty of the final-nucleus state spins; a 10% experimental error should be added. (Boboshin 2002) were obtained by joint evaluating the stripping and pickup reaction data. The values in parenthesis are the same as in Table 3.…”

“…In the procedure, some initial value E 0 (close to the assumed E nlj ) was chosen to use in calculating V(E 0 ) and Tables 3 and 4 below, where they are compared with the results of joint evaluation of the stripping and pickup reaction data (Bespalova et al 2001b;Bespalova et al 2002;Boboshin 2002) and with the predictions of the relativistic mean field theory (RMFT) (Typel and Wolter 1999). A good agreement with the available experimental and theoretical data was achieved, except for the 1s 1/2 state in the cases where this state is deeper than -60…”

Dispersive optical potential for nuclei with N and Z values changing toward the nucleon drip lines

“…In the analysis, we included experimental data on E expt nlj in the vicinity of the energy E F that were obtained by simultaneously evaluating data on the nucleon-stripping and nucleon-pickup reactions on the same nucleus. Such data were obtained for neutron and/or proton states in stable isotopes of Ca, Ti, Cr, Fe, Ni, Zn, Ge, Se, Sr, Zr, Сd, and Sn, and are given in [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”

“…For magic and nearly magic nuclei, there is an energy interval around E F where the imaginary part of the dispersive optical potential vanishes. Expressions (8) satisfy this condition owing to the exponent of n = 4 even in the case of choosing E p = E F and involve a smaller number of adjustable parameters. Expressions (9) are convenient since, in them, the surface component W d does not depend on the volume component W s .…”
