 Title: RESONANCE ENERGY TRANSFER IN COLLISIONS OF LiH $A^{1}\Sigma$ WITH Li ATOMS Creators: Melton, L. A.; Wine, P. H.; Chung, K.; Wong, M. Issue Date: 1978 Publisher: Ohio State University Abstract: Total quenching rates have been measured for specific vibration-rotation levels of LiH $A^{1} \Sigma$ with Li($^{2}S$) atoms. These rates are quite large; the cross-sections are in the range $100-600 \AA^{2}$. For $v^{\prime} = 5$, the rates peek near $J^{\prime} = 0$, and for $v^{\prime} = 6$ they peak near $J^{\prime} = 12$. These peaks correspond to minimum energy defects $\Delta E$ in the reaction $LiH A^{1} \Sigma, v^{\prime} , J^{\prime} + Li(^{2}S) \rightarrow LiH X^{1} \Sigma, v^{\prime\prime} , J^{\prime\prime} + Li(^{2}P) + \Delta E$ of $\sim 50$ $cm^{-1}$. Recent theoretical work leading to calculations of these rates will also be discussed. URI: http://hdl.handle.net/1811/10589 Other Identifiers: 1978-TB-07
