We have recorded the photoelectron spectrum of 7Li2 at 488 nm and 457.9 nm. Photodetachment transitions are observed between the X2(Sigma) u+ state of 7Li2 and the X1(Sigma) g+, a3(Sigma) u+, and A1(Sigma) u+ states of 7Li2. The electron affinity of 7Li2 was determined to be 0.437 +/- 0.009 eV. Additional spectroscopic parameters for the X2(Sigma) u+ of 7Li2 determined in this work are: Be equals 0.502 +/- 0.005 cm-1 which leads to re equals 3.094 +/- 0.015 Angstrom, (omega) e equals 232 +/- 35 cm-1, and D0 equals 0.865 +/- 0.022 eV.
