With the aim of studying the interaction of fast electrons with solid surfaces we have developed an experimental set-up based on electron stimulated desorption (ESD) coupled to time-of-flight (TOF) mass spectrometry. Poly(methyl methacrylate) and pol

Angular intensity distribution of molecular ions ejected in matrix-assisted laser desorption/ionization (MALDI) have been measured for two symmetrical positions of the laser beam with respect to the sample surface normal (+60° and −60°). It is sh
