摘要：

We report fully-quantum, close-coupling (CC) calculations of inelastic integral cross sections of mercapto radical (SH) collisions with He. Scattering calculations, which take into account the fine-structure of SH, are done on a grid of collision energies large enough to ensure converged state-to-state rate coefficients for temperatures ranging from 1 K up to 350 K. The calculated cross sections and rate coefficients exhibit sizeable, parity-dependent propensities. (C) 2009 Elsevier B. V. All rights reserved.
