  Electron elastic-scattering phase shifts and cross sections along with the
differential and total cross sections and polarization of low-frequency
bremsstrahlung upon low-energy electron collision with endohedral fullerenes
$A$@C$_{60}$ are theoretically scrutinized versus the nature, size and spin of
the encapsulated atom $A$. The case-study-atoms $A$ are N, Ar, Cr, Mn, Mo, Tc,
Xe, Ba, and Eu. They are thoughtfully picked out of different rows of the
periodic table. The study is performed in the framework of a model static
approximation. There, both the encapsulated atom $A$ and C$_{60}$ cage are
regarded as non-polarizable targets. The C$_{60}$ cage is modeled by an
attractive spherical annular potential well. The study provides the most
complete initial understanding of how the processes of interest might evolve
upon electron collision with various $A$@C$_{60}$. Calculated results identify
the most interesting and/or useful future measurements or more rigorous
calculations to perform.
