Electron impact total cross sections for H$_{2}$S and PH$_{3}$ for a wide energy range

In this paper we have computed total cross sections for H$_{2}$S and PH$_{3}$ using two different molecular codes, Quantemol N for low energy calculations and Spherical Complex Optical Potential for intermediate and high energies. We present rotationally elastic total cross sections for electron scattering from H2S and PH3, to demonstrate the possibility of producing robust cross sections from 0.01 eV to 2 keV using two different theoretical formalisms[1]. We use the commercial Quantemol-N formalism[2] for calculating total cross sections up to threshold of the target and the Spherical Optical Complex Potential (SCOP) method for calculating total sections beyond threshold up to 2 keV [3]. \\[4pt] [1] C.
