Photodisintegration of 7 Li and αt potential structure

The disintegration of the 7 Li by polarized and unpolarized photons with the energies up to 90 MeV is investigated in the framework of the α-t cluster model. The wave functions of the relative motion have been obtained by solving the Schroedinger equation with a few different potentials both in a bound state and in continuous spectrum. Two attractive potentials contained Pauli forbidden states and two other potentials contained repulsive cores were studied. One of two latter potentials was derived on the basis of attractive potential by the method of SUSY transformation. Photodisintegration cross section and Σ asymmetry are sensitive to the structure of αt interaction at small distances
