Scaling of the L-vacancy-production cross section at kiloelectronvolt-ion collisions

A method is proposed for determining the vacancy-production probability from the dependence of the emission cross section of Auger-electrons or characteristic radiation on the collision energy. Based on the generalization of the existing experimental data on the collisions of atomic particles in gas and solid phases, a universal character of the dependence of the vacancy production probability on the closest approach distance is established for the first time. Scaling is proposed that makes it possible to calculate an L-vacancyproduction cross section from the universal dependence.
