# MJK: A program to calculate observable quantities in electron–atom collisions

## Description

Abstract We describe a code which utilizes partial-wave amplitudes to calculate a variety of physical quantities studied in electron–atom scattering. For elastic scattering and excitation of atoms with arbitrary angular momenta in collisions with spin-polarized and unpolarized electrons, the program can calculate angle-integrated and angle-differential cross sections, the spin polarization of scattered electrons, the spin left–right (up–down) asymmetry, generalized STU parameters, and the statistical ...
