One-nucleon spectroscopy of light nuclei

Three-cluster model of radiative capture reactions in seven-nucleon systems. Effects of cluster polarization

“…The In Table 7, we compare the spectroscopic factors for the bound states in 7 Be and 7 Li nuclei calculated within the present model and the multicluster model of Arai et al [37] with available experimental data [60,66]. It was shown (see, e.g., [67]) that the spectroscopic factors of the ground state of mirror nuclei for the decomposition 4 He + 3 He and 4 He + 3 H are close to each other. This is confirmed by our calculations.…”

Cluster analogies for nuclei with a=6, 7, 9

“…The idea of "cluster analogies" can be explained more transparently by comparison of deuteron with 6 Li nucleus in the binary {τt} cluster representation, where 3 He is associated with heavy proton, but Li( , )t    processes of photodisintegration by linearly polarized photons can be predicted and explained, and it was confirmed experimentally.…”

“…These channels are interesting due to the several reasons: first of all these channels are isobaranalogous, and investigation of isobar-analogous nuclei (in our case 6 He- 6 Li- 6 Be, 7 Li-7 Be) is of interest from the point of view of charge independence of nuclear forces. In addition, within the isobar multiplets some features of the nuclei structure can be revealed [3].…”

“…In [1,2] Be+γ, have been performed. These channels are interesting due to the several reasons: first of all these channels are isobaranalogous, and investigation of isobar-analogous nuclei (in our case 6 He- 6 Li- 6 Be, 7 Li-7 Be) is of interest from the point of view of charge independence of nuclear forces.…”

Neutron capture by light nuclei at astrophysical energies

“…So for the independent checking of these results other program for the phases calculation was used. This program was independently developed by the outside producer and it is based on other computing methods for the wave function calculation and rather different ways of matching of the wave function with asymptotic [34]. On the basis of it the scattering phase equal to 89.9° was obtained for the potential (2) at resonance energy 921 keV (the laboratory system) and specifying of 500 thousand steps of the wave function calculation and matching of it with asymptotic at 30 Fm.…”
