A note on dissociative photoionization of neopentane in the 10-30 eV photon energy range
Abstract
The photofragmentation of neopentane in the photon energy range 10-30 eV with synchrotron radiation is analysed and compared with previous data on mass and photoelectron spectra of this molecule. A broad maximum due to a shape resonance in the ion yield of the most abundant fragment ions is observed around 16 eV photon energy along with Rydberg series converging to the 2a(sup -1 sub 1) ionization threshold. The analysis of the branching ratios of the main fragment ions hints at a preferential decay of the shape resonance through the ionization channel 3t(sup -1 sub 2).
