Detailed experimental analysis of photon echo polarization in a longitudinal magnetic field is performed for the first time at the simplest quantum transition __J__ = 1 ↔ __J__ = 0 for which the non-Faraday rotation of photon echo polarization plane was predicted. The echo was generated at the inter

✦ Synopsis
The cross section for impact excitation of J = 2 rotational levels of polar molecules in the ground slate is derived in an impact parameter formulation of the sudden approximation, assuming a dipole interaction.
.A simple expression for the rate coefficient is given and some results for escitntion of CN by protons and electrons are presented.
