%0 Journal Article %T Insights into the semiclassical Wigner treatment of bimolecular collisions %A L. Bonnet %J Physics %D 2013 %I arXiv %R 10.1063/1.4819954 %X The semiclassical Wigner treatment of bimolecular collisions, proposed by Lee and Scully on a partly intuitive basis [J. Chem. Phys. 73, 2238 (1980)], is derived here from first principles. The derivation combines E. J. Heller's ideas [J. Chem. Phys. 62, 1544 (1975); 65, 1289 (1976); 75, 186 (1981)], the backward picture of molecular collisions [L. Bonnet, J. Chem. Phys. 133, 174108 (2010)] and the microreversibility principle. %U http://arxiv.org/abs/1308.1527v1
