Photodisintegration and radiative capture in the N 2 H , N 3 H , N 3 He , 2 H 2 H , 2 H 3 He , 2 H 4 He , 3 He 3 H , 4 He 3 H , and 4 He 3 He channels are studied on the basis of the corresponding two-cluster potential models. The astrophysical S factors at low energies are calculated. It is shown that various electromagneticcharacteristics of light nuclei, including the Coulomb form factors at momenta of up to 4 F −1 , can be studied using a single set of intercluster interactions containing forbidden states and consistent with the phase shifts of the cluster low-energy elastic scattering. The calculated inelastic form factors have a second maximum at 3–4 F −1 , although it is lower than the experimental one. The orbital states are classified for the lightest cluster systems, and the phase shifts and intercluster potentials are separated on the basis of Young orbital schemes.

The astrophysical S -factor of p2H radiative capture in the energy range down to 1keV is considered in the potential cluster model with the classification of orbital states according to Young’s...

The two-cluster model is a phenomenological semi-microscopic approach to the study of multinucleon nuclear systems. In the framework of this model, interaction of nucleon clusters is described by the...

The possibility of describing available experimental data for the total cross sections of neutron radiative capture on ⁸Li at thermal and astrophysical energies was considered within the framework of the modified potential cluster model with the state classification of nuclear particles according to the Young tableaux. Our approach allows one to transmit available data in the energy range 0.1–1.0 MeV quite well, and predicts the behavior of the total cross sections at super-low energies, down to 25.3 × 10⁻⁹ MeV.
