Abstract
The quantum dynamics of the rotational quenching of the (MgH+)-Mg-24(X-1 Sigma(+)) molecular cation interacting with He-4(S-1) as a buffer gas, at relative temperatures ranging from 1 K down to millikelvins, is described by accurate close coupling scattering calculations on an ab initio potential energy surface. The efficiency of the process is quantitatively analyzed by employing the ab initio quenching rates and cross sections and effective decay rate values are obtained from simple unimolecular kinetics over a broad range of trap conditions.
