State-selective electron capture processes in collisions involving boron ions

A full theoretical treatment of electron capture processes using ab initio configuration interaction methods within, according to the collision energy range concerned, a semiclassical or a quantal collisional formalism including translation effects has been developed recently. An application for collisions involving boron, an important impurity in fusion reactors, is presented on examples of the ground state: B3+(1s(2)) + He, B4+(1s) + H, and the metastable ion B3+(1s2s) + H reactions.
