โฆ Synopsis
Resonant scattering of low energy electrons from naphthalene has been investigated using electron transmission spectroscopy. The transmission spectrum of naphthalene yields a value of -0.20 f O-OS eV for the fast electron affinity. The first and second excited states ofCroHg are detected at 0.96 f 0.1 eV and 1.55 f 0.13 eV_ Resonant structure is also observed at 5.29 i 0.1 eV and 7.55 -+ 0.05 eV; it is suggested that the former resonance is the previously unidentified peak in the threshold electron excitation spectrum of Compton and co-workers.

In scatterins of slow electrons from benzene vapour in addition to the known resonance at 1.1 eV a second resonance at I.7 eV is discovered, formerly observed only for benzene derivatives. The experimental analysis enables the identification of both resonances as the predicted opticaIIy inactive col
