Abstract
The differential cross section for the nuclear beta-decay process indu ced by Coulomb collisions involving a parent nucleus is calculated wit hout invoking the Born approximation. The calculation have been perfor med with the exact Coulomb functions describing the relative motion of colliding particles. The mechanism relying on the collision-induced b eta(-) decay of stable nuclei that belong to the main sequence is used as a basis for explaining the formation of by-passed isotopes in stel lar matter. The relative abundances calculated for by-passed isotopes under the assumption of this mechanism comply well with experimental d ata.
