Measurements of collisional loss of optically trapped Rb atoms are presented for excitation of the colliding atoms by light tuned near the 5[ital S][sub 1/2][r arrow]5[ital P][sub 1/2] transitions of [sup 85]Rb and [sup 87]Rb. Using the [ital P][sub 1/2] state allows the effects of spontaneous emission on excited-state collisions to be studied with minimal complications arising from hyperfine structure. The shapes of the collision spectra are nearly identical for the two isotopes and are consistent with a simple model for the role of spontaneous emission during the collision.
