It is proposed to investigate the role which collisional                   processes play in modifying the interaction of radiation fields                 with atoms.  The techniques to be used involve the derivation of                a transport-type equation which accounts for both the atom-field                and collisional interactions.  Work on the inclusion of                         polarization effects and velocity-changing collisional effects                  will be combined to obtain a comprehensive theory of line shapes                in four-wave mixing.  It is proposed to explain pressure-induced                extra resonances in a unified manner using conservation of energy               arguments, with applications to four wave mixing, quantum beats                 and photoionization.  Studies will be undertaken of the                         interaction of radiation fields with trapped atoms, including                   transient responses, radiation emitted and the role of                          collisional processes on the atom-field interaction.
