X-ray radiation spectra during the ion irradiation of solids

A dynamic theory of the X-ray uncharacteristic radiation is considered, the radiation arising from the deep ion collisions with solid targets. The collision process is described within the limits of the transitional quasimolecular model. The system investigated experimentally in the effective potential approach is Ni+-Ni for which calculations are made of the lone electron energy levels and dipole matrix elements, needed to calculate the X-ray radiation cross sections versus R, R being the colliding atom internuclear distance
