This work presents an empirical expression that allows one to estimate
the integrated oscillator strength for multi-ionization of an atomic
target reaction by electron impact as a function of the target final c
harge state. The individual ionization process is considered as a tran
sition into the continuum and described through the Bethe formula. The
results are compared with data for noble gases available in the liter
ature.
