Experimental study of the removal of excited state phosphorus atoms by H${}_2$O and H${}_2$: implications for the formation of PO in stellar winds

Kevin M. Douglas, David Gobrecht, John M. C. Plane

The reactions of the low-lying metastable states of atomic phosphorus, P(${}^2$D) and P(${}^2$P), with H${}_2$O and H${}_2$ were studied by the pulsed laser photolysis at 248 nm of PCl…
