Abstract
This paper reports computational results of the total (complete) and total ionization cross- sections, for electron impact on Uracil (C4H4N2O2) and PO3OH for impact energies from the ionization threshold to 2 keV. The total cross-section is evaluated using quantum mechanical approach using Spherical Complex Optical Potential (SCOP) presented as sum of the elastic and inelastic cross-sections. The ionization cross-sections are extracted from total inelastic cross-section using Complex Optical Potential–ionization contribution (CSP-ic) method. The present results are, in general, found to be in good agreement with previous theoretical results. In absence of any theoretical or experimental data, present results for PO3OH will serve to fill the void in the data base and may also inspire the experimentalists for some measurements as it is very important target.
