A. Poquerusse et al., WIDTH FUNCTIONS FOR THE PERTURBATIVE DIPOLE IMPACT LINE-BROADENING THEORY WITH CORRECT UNITARITY CUTOFF, Journal of quantitative spectroscopy & radiative transfer, 56(5), 1996, pp. 797-801
In this work accurate analytic formulas are given that enable the corr
ect determination of the minimum impact parameter rho(min)(upsilon) fo
r isolated ion lines in the dipole approximation. Copyright (C) 1996 E
