Unitary Pole Approximation For 16O S12state And 40ca P32state When Coulomb Interaction Is Included

Abstract The form factor of a separable interaction between a pair of particles is an important input in a three body calculation for a transfer reaction. The three body equations of Alt Grassberger and Sandhas have been solved for a system of three particles viz.p n and 16Oand p n and 40Ca when coulomb interaction is included between the particle pairs. The input in this calculation i.e. the two body t-matrices representing the interaction between the pairs of particles is taken to be of a separable form conforming to the bound state of the pair. The form factors of the total interaction between the particle pairs are constructed using the prescription of Ueta and Bund.
