LIGHT PARTICLES INTERACTING WITH ORGANIC-MOLECULES

Slow electron scattering from CH4, and thermal positrons annihilating with a variety of organic molecules, will first be discussed, the major role of molecular polarizability being the focal point. In the same context, initially neutral carbon clusters with an added, but now bound, electron will be considered, and in particular for C-60(-) the role of polarizability will again be stressed. Some attention will also be paid to electron-electron interaction in C-60(-). Photoelectron spectroscopic data on ionization potentials for both linear and terminated polyacenes will then be briefly considered, both the role of hole localization and hole-hole interaction being referred to in these quasi-two-dimensional systems. Finally some directions for further work are proposed. (C) 1993 John Wiley and Sons, Inc.
