Dispersion (asymptotic) theory of charged-particle transfer reactions and nuclear astrophysics

Аннотация

A new asymptotic theory is proposed for the peripheral transfer A(x,y)B reaction at low energies within the three-body (A, a and y) model by combining the dispersion theory and DWBA, where x= y + a, B= A + a, and a is atransferred particle. The results of the analysis of the differential cross sectionsof the proton transfer 9Be(10B, 9Be)10B reaction at the 10B projectile energy of 100 MeV populating the ground and excited states of the residual nucleus are presented. New estimates and their uncertainties are obtained for values of the asymptotic normalization coefficients for 9Be + p → 10B and for the astrophys- ical S factors at stellar energy of the radiative capture 9Be(p,γ)10B reaction.
