In this paper, the isospin dependent nucleon-nucleus optical potential theory is introduced on the basis of the effective Skyrme interactions. From the view of the many-body theory, the nucleon optical potential can be identified with the mass operator of the one-particle Green function. The first and second order mass operators of the one particle Green function in nuclear matter are derived, and the real and imaginary parts of the optical potential for finite nuclei are obtained as usual by applying a local density approximation. Our results, in most cases, can be derived and expressed analytically. From an extensive comparison with experimental data of various quantities of interests, it is concluded that for certain versions of Skyrme interactions without parameter adjusting the agreement between theory and experiments can be obtained satisfactorily. We define the ratio of the difference and summation of the neutron and proton nonelastic cross sections as the isospin effect value. The calculated results show that the isopin effect value decreases as the incident energy increases and increases as the asymmetric parameter α 0 = (N -Z)/A of the target nucleus increases.

“…[13] and for low-to-high mass numbers in Refs. [10,14]. These issues were tested simultaneously for the first time in our recent work [1] on the elastic scattering of 6 Li +p, where the JLM potential was applied both to a low mass projectile and at low energies, 2.7-4.8 MeV/nucleon.…”

“…This potential was applied in Refs. [9][10][11] to medium and heavy mass stable nuclei at energies above 10 MeV/nucleon, with only slight adjustments to the imaginary part. It should be noted that Jeukenne, Lejeune, and Mahaux parametrized their numerical results for the real and imaginary parts of the optical potential in an analytical form.…”

Probing the cluster structure ofLi7via elastic scattering on protons and deuterons in inverse kinematics

et al. 2016

Elastic scattering measurements were performed for the 7 Li +p system in inverse kinematics at energies of 16, 25, 35, and 38.1 MeV and for the 7 Li +d system at 38.1 MeV. The heavy ejectiles were detected by the large acceptance MAGNEX spectrometer at the Laboratori Nazionali del Sud in Catania, Italy. The results are analyzed using the Jeukenne-Lejeune-Mahaux and continuum discretized coupled channel frameworks. In the latter case the cluster structure of 7 Li proves to be critical for the theoretical interpretation of the experimental results.

“…[14] while for lower mass numbers in Refs. [12,15], where the validity of the local density approximation is under a severe test. Both these issues were confronted in our recent work of proton elastic scattering in inverse kinematics with the radioactive nucleus 17 F [16].…”

“…This potential was derived by Jeukenne-Lejeune-Mahaux [10] and applied in Refs. [11][12][13] for medium-and heavy-mass stable nuclei and for energies above 10 MeV/u with slight adjustments only on the imaginary part. The applicability of the JLM method for lower energies (7 E/A 24) was tested in Ref.…”
