Scattering Processes of Excited Muonic Atoms by Molecular Hydrogen
ABSTRACT The coupled-channel approach of an excited exotic atom scattering from a hydrogen molecule in the rigid-rotator approximation
is developed. The K-matrix method is used to solve the set of coupled collisional equations in the space-fixed (SF) framework for the systems
pμ+H2, dμ+D2, pμ+D2, and dμ+H2. The elastic and Stark mixing cross-sections for scattering on molecular ortho- and para-states are calculated for the principle
quantum number n = 2 and collisional energies E≥0.1 eV.
