From the broadening of the level crossing (Hanle effect) signal with increasing pressure of rare gas collision partners, together with direct level crossing measurements on fluorescence from rotationally transferred $S_{2}$ molecules, we can estimate the amount of coherence retained throughout a rotational transfer collision. The degree of retention is quite high -- of the order of 80% in the case of collisions with helium. en_US dc.format.extent 113578 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title COHERENCE RETENTION IN THE COLLISIONAL RELAXATION OF THE $B^{3}\Sigma_{u}^{-}$ STATE OF $S_{2}$ en_US dc.type article en_US
