Abstract

Present paper reports calculations of total ionization cross sections ( Q ion) for simple but important alcohols (CH 3OH, C 2H 5OH, 1-C 3H 7OH) on electron impact with incident energies ( E i ) ranging from ionization threshold ( I) of the target to 2 keV. We have employed well established Spherical Complex Optical Potential (SCOP) formalism to evaluate total inelastic cross sections. We have also made an attempt to improve original Staszeweska model by considering Δ energy dependent and made to vary within the range ηI ≤ Δ( E i ) ≤ I. The total ionization cross sections are calculated using improved complex scattering potential-ionization contribution (ICSP-ic) method. The present results along with available experimental and other theoretical data are presented graphically.
