摘要：

Penning ionization of naphthalene and anthracene with He*(2(3)S) atoms has been studied by means of simultaneous detection of collision energy and electron energy. The anisotropy of interaction potentials between He*(2(3)S) atoms and the target molecules has been found on the basis of the collision energy dependences of partial Penning ionization cross-sections. Based on the analyses of collision energy dependences and electron correlation calculations, assignments of ultraviolet photoelectron spectra are discussed. (C) 1998 Elsevier Science B.V.
