“…On the first glance, this method seems to be artifical. But, as a matter of fact, transmission coefficients of some hip-optical model potentials available in literature [45,46] exhibit just this particular behaviour at low energies, commonly referred to as "oddeven staggering". Such a behaviour of the potential is responsible for formerly made observations of parity dependent cross sections for states with equal spin J in the course of HF-calculations for the system t2C+OLi [4].…”

Reactions between 6Li and 6Li were studied in the laboratory energy range of 2-16 MeV. Angular distributions and excitation functions were measured for various proton, deuteron, triton and e-channels. In addition excitation functions were obtained for five 7-transitions in ~~ and the ground-state transitions in both 7Li and VBe. Detailed statistical model calculations were performed under various assumptions concerning the formation of the compound nucleus. It is concluded that a smooth cutoff of the entrance channel angular momenta yields the only consistent description for both angular distributions and excitation functions. Only a few proton channels are dominated by compound nucleus decay. All other channels reflect the complex structure of 6Li which causes a variety of direct reaction modes.Nuclear Reactions: 6Li + 6Li at 2 < Ela b ~ 16 MeV; measured angular distributions and excitation functions of p, d, t, e-channels and y-transitions in 7Li, 7Be, l~ statistical model calculations; deduced fusion cross section; reaction mechanism inferred.

Proton inelastic excitation spectra of 12C have been measured imposing a coincidence with alpha decay to aB%s" and SBe2.9MeV. In plane angular correlations have been obtained for the main structures observed in the spectra. Comparison with DWBA correlation functions permits a 2 + assignment for all the groups in the 20-30MeV excitation range. The percentage of the E2-EWSR exhausted in the same range is in agreement, within the uncertainties indicated, with that derived from the inelastic scattering of other particles.

“…Analysis of the p+ 8 He elastic scattering, which will be reported elsewhere, revealed that those of 8 He are 2.22±0.27 fm and 2.02±0.52 MeV, respectively, which are similar to those of 6 He. Compared with these values, LS amplitudes of neighboring even-even stable nuclei [13,14,15] and global optical potentials [16,17] are considerably different. The LS amplitudes of stable nuclei are distributed at around 5 MeV, whereas those of 6 He and 8 He are as small as 1.3 and 2.0 MeV.…”

Abstract. The vector analyzing power has been measured for the elastic scattering of neutronrich 6 He and 8 He from polarized protons at 71 MeV/A making use of a newly constructed solid polarized proton target operated in a low magnetic field of 0.1 T and at a relatively high temperature of 100 K. An optical model analysis revealed that the spin-orbit potentials for 6 He and 8 He are characterized by shallow and long-ranged shape compared with the global systematics of stable nuclei. Such a characteristics reflect a diffused density distribution of the neutron-rich isotopes.
