Electron energy loss spectra of disilane have been recorded over an excitation energy range of 20 eV employing electrons of 20 and 200 eV incident energy for scattering angles of 0/sup 0/--90/sup 0/. Every transition detected except one appears at an energy consistent with the first observed members of Rydberg series converging to one of four possible ion states. The first two observed transitions belong to (2a/sub 1//sub g/)/sup 2/..-->../sup 1//sup ,//sup 3/(2a/sub 1//sub g/,4s) dipole forbidden channels appearing at excitation energies of )similarreverse arrowto)6.3 and 7.05 eV for the triplet and singlet, respectively. Evidence is presented for the identification of additional forbidden transitions as well as possible low-lying valence transition
