Photodisintegration of 4He nucleus into p3H and n3He channels in the   potential cluster models
  Processes of direct cluster photodisintegration of 4He nucleus into p3H and n3He channels are considered on the base of two-cluster potential models. Intercluster interactions being in agreement with elastic scattering phase shifts and characteristics of the bound state of a nucleus have, in some cases, forbidden states. The scattering phase shifts and potentials are separated in the channels with minimum spin on the base of Young schemes and isospin states.
