Abstract

The population dynamics of the lower energy excited states of atomic strontium, namely, 1D 2, 3D J , 3P 2, 3P 1 and 3P 0, have been investigated by time-resolved laser-induced fluorescence following pulsed laser excitation to the Sr[5s5p( 1P 1)] state at 760 K in presence of the noble gases Ne, Kr and Xe. In addition, the 1P 1 and 3P 1 states were monitored by spontaneous emission under intentionally quantified conditions of radiation trapping for Sr( 1P 1). The kinetic model employed yields a set of kinetic rate constants, radiation data, collisional propensity rules and the correlation of collisional cross-sections for all the noble gases with potential well depth.
