Mass spectrometric investigation of desorbed ions from a valine sample by252Cf fission fragments

Summary Spectra of positive and negative secondary ions desorbed from a valine sample by²⁵²Cf fission fragments were measured in a new time-of-flight mass spectrometer. The outstanding features of the obtained results, including fragmentation, cationization and clustering are discussed.
