Abstract:

The work done described in siis report is divided into two major parts 1 a study of ion-molecule and molecule-molecule collisions in the range of 200-2000 ev energy, with applications to meteor physics and 2 a study of electron-molecule and molecule-molecule collisions at energies of a few volts of less, with applications to at mospheric reactions. Excitation and charge transfer in collisions of N2, Ar, Ne, K, Na, Mg, and Ca with N2 and Ar have been studied. Work has been extended to meas uring momentum transfer cross sections for these colissions, so as to evaluate the fraction of energy lost which goes into radiation of a given wavelength which is excite Author
