Manuscript Title: MJK: a program to calculate observable quantities in electron-atom collisions.
Authors: A.N. Grum-Grzhimailo
Program title: MJK
Catalogue identifier: ADRI_v1_0
Distribution format: gz
Journal reference: Comput. Phys. Commun. 152(2003)101
Programming language: Fortran.
Computer: DEC Alpha 667MHz.
Operating system: UNIX.
RAM: 90M words
Word size: 64
Peripherals: disc.
Keywords: Electron-atom scattering, Scattering amplitudes, Excitation, Differential cross sections, Spin polarization, Spin asymmetry, State multipoles, Statistical tensors, Atomic physics.
Classification: 2.4.

Nature of problem:
Angle-integrated and angle-differential physical observables in elastic and inelastic electron-atom scattering, evaluated from partial-wave T-matrix elements.

Solution method:
Density matrix and statistical tensor formalism ([1] and references).

Unusual features:
The program can be run interactively. It is possible to use an unformatted output file from the flexible asympotic FARM package [2] as an input file to the program.

Running time:
Typical calculations take a few seconds on DEC Alpha 667 MHz workstation depending on complexity of the problem.
