Partial widths of feshbach funnel resonances in the Na(3p) � H2 exciplex

We have located five zero-angular-momentum resonance states in the funnel associated with the lowest conical intersection of the Na (3p) · H2 exciplex, and we have characterized the four narrowest of these in terms of total and partial widths. The resonant contributions of the metastable states to state-to-state energy transfer greatly exceed the background contributions. © 1993 John Wiley & Sons, Inc.
