A Fortran 90 program is presented, namely Ion-Atom-Wave (IAW), which calcul
ates total, single and double differential cross sections for the single io
nization of atomic and molecular hydrogen-like targets and helium-like targ
ets by both light-and-heavy-ion impact. The cross sections are evaluated wi
thin the continuum distorted-wave final-state (CDW) and the continuum disto
rted-wave eikonal-initial-state (CDW-EIS) approximations. IAW calculates cr
oss sections within the wave treatment. This program extends a previously p
ublished program ION (D.S.F. Crothers and M. McCartney, Comput. Phys. Commu
n. 72 (1992) 288) which calculated the total, single and double differentia
l cross sections for the ionization of hydrogen-like targets by fully strip
ped ions. (C) 1998 Elsevier Science B.V.
