Abstract
Exothermal nuclear reactions that become forbidden due to Coulomb repulsion in the limit are investigated. is the cross section and is the center of mass energy.] It is found that any perturbation may mix states with small but finite amplitude to the initial state resulting in finite cross section (and rate) of the originally forbidden nuclear reaction in the limit. The statement is illustrated by modification of nuclear reactions due to impurities in a gas mix of atomic state. The change of the wave function of reacting particles in nuclear range due to their Coulomb interaction with impurity is determined using standard time-independent perturbation calculation of quantum mechanics. As an example, cross section, rate and power densities of impurity-assisted nuclear reaction are numerically calculated. With the aid of astrophysical factors cross section and power densities of the impurity-assisted , , , , , , , and reactions are also given. The affect of gas mix-wall interaction on the process is considered too.
