Abstract
A new computational code based on the method of continued fractions is developed to study low-energy electron scattering by polyatomic molecules with arbitrary symmetry. As a first application, this code is used to study elastic electron scattering by four representative molecules with different symmetries, viz., H 2 , CH 4 , H 2 O, and NH 3 . The calculated physical quantities such as reactance K ̃ matrices, differential cross sections, etc, converge rapidly. Also, our calculated cross sections are in good agreement with other available theoretical and/or experimental data, confirming that this is an efficient method for studying electron molecule scattering.
