Adhesion coefficients in the strong-absorption model

An effect of a direct mechanism of inelastic scattering on probability of compound nucleus production has been estimated. An explicit form of adhesion coefficients as well as S matrix elements of elastic and inelastic scatterings of spinless particles with deformed even-even nuclei in a strong-absorption model have been analytically obtained. The α+232Th reaction studied earlier was considered to estimate obtained analytical forms of adhesion coefficients. Adhesion coefficients with provision for the radius of alpha particle interaction and a thorium nucleus according to the formulae Rsub(0)=1.41(Asub(1)sup(1/3)+Asub(2)sup(1/3)) have been calculated. Given are graphical dependences of elastic scattering amplitude and adhesion coefficients on orbital momentum in the α+232Th reaction. It is shown that the accountancy of the direct mechanism of inelastic scattering is markedly revealed near the orbital momentum corresponding to a trajectory tangent. The estimation of adhesion coefficient carried out in the approximation of abrupt amplitude drop in a point of critical orbital momentum, shows that the formula derived overestimates its value two times
