Proposal to Produce Velocity-Selected and State-Selected Molecular Beams Usingthe Ballistic Effect

摘要

A method for producing molecular beams containing molecules in the desiredinternal (rotational, vibrational, electronic, etc.) state and traveling with the desired velocity is proposed. The method is illustrated by describing the circumstances that would lead to a state-selected and velocity-selected N sub 2 beam resulting from collisions with Li(+) with N sub 2.
