Abstract
The recent development of solid state lasers with very narrow bandwidth operating in the blue region of the electromagnetic spectrum has allowed new expts. to be considered which were previously unfeasible. An expt. combining the resonant interaction of continuous wave radiation at 422 nm with electron impact ionization of calcium is described. By coherently exciting the atom, ionization from the aligned and oriented target can reveal new insight into the influence of the initial target state on the reaction. Deep, narrow interference min. which have been obsd. in non-coplanar differential cross sections of helium and neon are also expected in calcium, which has a similar electronic structure. This structure is explored as a function of laser prepd. target parameters to ascertain the underlying phys. reasons for this min. [on SciFinder (R)]
