Abstract The operation of the code MET_cross for the solution of the semiclassical multichannel eikonal theory for electron-atom scattering is described. Also described is a second code, MET_states, which utilizes the results produced by MET_cross to generate a complete set of state multipoles and coherence and alignment parameters needed to characterize the polarization properties of the radiation emitted in the decay of the metastable atomic states excited in the collision. Included also is a discus... Title of program: MET_states Catalogue Id: ADAY_v1_0 Nature of problem Given the complex scattering amplitudes fi->n(theta) for excitation of atomic states |n>, by intermediate to high energy electrons, calculate the state multipoles <T(J'J)KQ+> characterizing the coherence among the magnetic substates and the correlation between the scattered electron and the photon emitted in the decay of the state |n> under the influence of the Q-component of a tensor T of rank K. Also, completely determine the degree of polarization of the emitted radiation by computing the Sto ...
