Abstract
The H+ +H2 reaction is studied by means of both exact and statistical quantum
methods. Integral cross sections for processes initiated with rotationally excited
H2(v, j = 1) to produce molecular hydrogen in its rotational ground state are
reported up to a value of the collision energy of 3 eV. Rate constants for state-
to-state transitions between different H2 rovibrational states are calculated up to
3000 K. Special emphasis is made on ortho/para conversion processes in which
the parity j of the H2(j) states changes.
