Description
Summary:The investigation of fragmentation processes in cytosine molecules caused by an electron impact was carried out using crossed electron and molecular beams and the AM1 quantum-chemical method. The probable schemes of cytosine fragmentation, absolute values of partial ionization sections, and their energy dependences are presented. It is shown that the value of the total section of formation of positively charged fragments is 2.9 times higher than the section of the molecular ion formation. The calculation of the parameters of the cytosine molecule and its ions was performed.
