Results from a 4{pi} solid angle measurement of the inclusive reaction ({pi}{sup +},{pi}{sup 0}) on {sup 2}H, {sup 3}He, and {sup 4}He at incident pion energies of T{sub {pi}{sup +}}=70, 118, 162, 239, and 330 MeV are presented. The single charge exchange total cross sections were determined, and are compared to previous results and simple models of {pi}{endash}few-nucleon interactions. On the helium isotopes a strong damping of the cross sections in the {Delta}(1232) energy region is observed. Total cross sections of the breakup reaction {pi}{sup +}+{sup 2}H {r_arrow}{pi}{sup +}pn are also given. {copyright} {ital 1999} {ital The American Physical Society}
