Heavy particles from silver targets bombarded by ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ heavy projectiles have been identified using a counter telescope and bidimensional analysis of $\Delta E$ and $E$ data. Energy distributions have been measured for Li, Be, B, C, N, and O nuclei. Angular distributions exhibit a maximum which is related to the distance of closest approach. The largest cross sections are observed for ${}_{}{}^{11}{}_{}{}^{}\mathrm{B} \mathrm{}(-1p)\mathrm{}$ and ${}_{}{}^{13}{}_{}{}^{}\mathrm{C} \mathrm{}(+1n)\mathrm{}$ single transfer. It is emphasized that the total cross section for the loss of a proton by the projectile is 60 times the cross section for the pickup of a proton. The products of transfer reactions are mainly formed in excited states, but the angular distribution does not depend on the degree of excitation, at least for the lowest excited states.
