A. Alpha particles B. Neutrons C. Electrons D. Protons
Explanation: In the mass spectrometer, the sample which is to be analysed is bombarded with electrons, which leads to the formation of the ions. The ions are sorted out by accelerating them through electric and magnetic field. A record of the number of different kinds of ions is called mass spectrum.
