Analytic formulas are given for the total cross sections sigma for charge transfer collisions of hydrogen atoms and ions with gaseous atoms and molecules. The cross sections considered are sigma/sub 10/, sigma/sub 0//sub -//sub 1/, sigma/sub 1//sub -//sub 1/, sigma/sub 01/, sigma/sub -//sub 10/, and sigma/sub -//sub 11/, where the subscripts represent the initial and the final charge state of the hydrogen. The functionl forms of the formulas are modifications of the semiempirical formula for sigma/sub 10/ given by Green and McNeal. Values of adjustable parameters in the formulas have been determined by least-squares fits to a compiled set of experimental data and are given in a table. The curves given by the formulas are plotted in graphs together with the data. The root-mean-square deviation of the data from the formulas is typically about 20% except when there are large discrepancies among the measurements. Experimental data through 1982 are shown on the graphs; references through mid-1986 are listed. copyright 1987 Academic Press, Inc.
