Electronic processes induced by high energy H+, H{2/+} and H{3/+}-ions: A scaling relation
Abstract
A scaling relation is proposed which interrelates measurable quantities in the field of atomic collision physics performed with high velocity H+, H{2/+} and H{3/+}-ions. The relation may be written as 10053_2005_Article_BF01436673_TeX2GIFE1.gif Q(H^ + ) - 2*Q(H_2^ + ) + Q(H_3^ + ) = 0, where Q denotes an excitation or ionization cross section or a total or differential secondary particle yield evaluated at the same projectile velocity. The scaling relation will be tested by comparison with experimental data of yields and spectra from ion-induced secondary electron emission measurements and with cross section data for excitation and ionization of atoms and molecules. In general very good agreement is observed for high projectile velocities ( v>2 a.u.).
