Description
A new empirical formula for the average equilibrium charge-state, anti q, of heavy ions observed after traversal of various foils is presented. The formula is anti q/Z1=[1-exp(-1.25X+0.32X2-0.11X3)] [1-0.0018(Z2-6)√X+0.00001(Z2-6)2X], where Z1 and Z2 are the ion and target foil atomic numbers respectively, and X is the reduced ion velocity as defined by Nikolaev and Dmitriev. The present formula is useful for the collision range Z1>=8,4<=Z2<=79 and E<6 MeV/amu, to within an accuracy of Δanti q/Z1<0.04. (orig.)
