Total state-selected and state-to-state absolute cross sections for the reactions Ar{sup +}({sup 2}{ital P}{sub 3/2,1/2})+H{sub 2}({ital X},{ital v}=0){r arrow}Ar ({sup 1}{ital S}{sub 0})+H{sup +}{sub 2}({ital {tilde X}},{ital v}{prime}) (reaction (1)), ArH{sup +}+H (reaction (2)), and H{sup +}+H+Ar (reaction (3)) have been measured in the center-of-mass collision energy {ital E}{sub c.m.} range of 0.24--19.1 eV. Absolute spin--orbit state transition total cross sections ({sigma}{sub 3/2{r arrow}1/2},{sigma}{sub 1/2{r arrow}3/2}) for the collisions of Ar{sup +}({sup 2}{ital P}{sub 3/2,1/2}) with H{sub 2} at {ital E}{sub c.m.}=1.2--19.1 eV have been obtained.
