Resonant transfer excitation (RTE) was observed and RTE Auger-electron cross sections were measured for the formation of F{sup 6+} (1{ital s}2{ital l}2{ital l} {prime}) states in collisions of 0.25--2 MeV/u F{sup 7+}(1{ital s}{sup 2} {sup 1}{ital S},1{ital s}2{ital s} {sup 3}{ital S}) with H{sub 2} and He at zero degrees with respect to the beam direction. The measured Auger-electron differential cross sections agreed well with a modified treatment of the usual impulse approximation and the recent angular dependence theory of RTE by Bhalla (Phys. Rev. Lett. 64, 1103 (1990)), thus confirming the selective population of the {ital M}{sub {ital L}}=0 magnetic substate in RTE processes. The extracted resonant excitation scattering strengths for the 1{ital s}2{ital p}{sup 2} {sup 2}{ital D} and 1{ital s}(2{ital s}2{ital p} {sup 1}{ital P}){sup 2}{ital P}{sub +} states were found to be (35{plus minus}2){times}10{sup {minus}19} and (14{plus minus}2){times}10{sup {minus}19} cm{sup 2} eV, respectively. These two states showed the strongest {ital KLL} RTE signature as predicted by theory.
