Abstract: The mechanism of radiation damage to 2,5-diketopiperazine (DKP, C$_4$H$_6$N$_2$O$_2$) molecules in the gas phase upon interaction with He$^{2+}$ ions with an energy Ep = 4 keV/u has been investigated. The relative cross sections of various elementary processes occurring in single collisions of DKP with ions have been measured for the first time. The channels of fragmentation processes of singly charged ions have been studied experimentally. The DFT method was used to calculate the geometry of molecules and singly charged DKP ions, as well as the energies of the main experimentally observed channels of fragmentation of these ions.
Keywords: electron capture, dipeptides, molecular ion fragmentation.
