摘要: Anion photoelectron spectra taken at various photodetachment wavelengths have been obtained for GaX2−, Ga2X−, Ga2X2−, and Ga2X3− (X=P,As). The incorporation of a liquid nitrogen cooled channel in the ion source resulted substantial vibrational cooling cluster anions, resulting resolved progressions all species except Ga2X2−. Electron affinities, electronic term values, frequencies are reported compared to structure calculations. In addition, similarities differences between phosphorus arsenic-containing isovalent discussed.
