Abstract

In the Standard Solar Model a central role in the nucleosynthesis is played by reactions of the kind $${}_{Z_1}{}^{A_1}X{}_1+{}_{Z_2}{}^{A_2}X{}_2\to {}_{Z_1+Z_2}{}^{A_1+A_2}Y+\gamma$$, which enter the proton-proton chains. These reactions can also be studied through the inverse photodisintegration reaction. One option is to use the Lorentz Integral Transform approach, which transforms the continuum problem into a bound state-like one. A way to check the reliability of such methods is a direct calculation, for example using the Kohn Variational Principle to obtain the scattering wave function and then directly calculate the response function of the reaction.
