The formation and decay of the 2[ital p]'' electronic excited states of the rare gases neon, argon, krypton, and xenon in a buffer gas of either helium or neon has been studied by pulse radiolysis techniques. The formation rate constants for these states are all greater than [similar to]2[times]10[sup [minus]9] cm[sup 3] s[sup [minus]1], precluding atom-atom collisional processes and supporting a subexcitation electron mechanism. The rate constants generally show a trend [ital k][sub Xe][gt][ital k][sub Kr][gt][ital k][sub Ar][gt][ital k][sub Ne]. Quenching rate constants for the deactivation of some of the 2[ital p] levels are also reported.
