✦ Synopsis

The emission spectrum of the A'Z: -X 'El band of Na, following Ar-ion laser excitation of the B'II, state has been recorded as a function of excitation frequency and cell temperature.

The band profile is shown to be inconslstent with a thermalised excited state. The spectrum is interpreted as being the result of a collisionally assisted curve crossing to the metastable (2)'2; state, and subsequent infrared radiative decay to the A state.
