The codeposition of C{sub 60} vapor with excess argon and argon resonance radiation has produced strong new absorptions at 973 and 1068 nm in solid argon at 11 {+-} 1 K. A similar experiment with CCl{sub 4} added to serve as an electron trap reduced the yield of the 1068-nm band with little effect on the 973-nm absorption. The 973-nm band is assigned to C{sub 60}{sup {sm_bullet}+} produced by photoionization and the 1068-nm band to C{sub 60}{sup {sm_bullet}-} formed by electron capture. These identifications are in excellent agreement with glassy matrix, solution, and photoelectron spectra.
