© 2015 American Physical Society. Electron elastic-scattering phase shifts and cross sections as well as total cross sections of low-frequency bremsstrahlung and its angular-asymmetry and polarization parameters upon low-energy electron collision with endohedral fullerenes A@C60 are theoretically scrutinized versus the nature, size, and spin of the encapsulated atom A. This is achieved by choosing Ar, Xe, Ba, Cr, Mn, and Eu as the case-study atoms A. The aim is to uncover the variety of effects which might occur in the above processes rather than to make thorough predictions for one particular spectrum. To that end, the study makes use of a simple model static-exchange approximation. There, both the encapsulated atom A and the C60 cage are regarded as nonpolarizable targets and the C60 cage itself is modeled by an attractive spherical annular potential well. Calculated results identify the most interesting and/or useful future measurements or more rigorous calculations to perform.
