SCATTERING OF MAGNETICALLY ANALYZED F(P-2) ATOMS AND THEIR INTERACTIONS WITH HE, NE, H-2 AND CH4

An improved source of a beam of fluorine atoms has been characterized by magnetic analysis of sublevels for F(2P). Ground state and lower lying excited state potential energy curves for the interaction of fluorine atoms with He, Ne, H2 and CH4 have been obtained from measurements of integral scattering cross sections at thermal energies. The results for the rare gas systems are discussed in connection with previous work on Ar, Kr, and Xe fluorides; those for the H2 and CH4 systems provide information of fine structure effects on the long range pan of entrance channels for reactive potential energy surfaces. © 1990.
