Abstract
Ionization of excited helium atoms in states due to collisions with the polar molecules N has been studied in a thermal energy crossed-beam experiment. A large ionization signal from these low Rydberg states is observed even though there is insufficient energy available from rotational , relaxation transitions of the molecule. In order to explain our observations, large transitions must be postulated.
