  We present a comprehensive set of theoretical results for differential,
integrated, and momentum transfer cross sections for the elastic scattering of
electrons by beryllium, magnesium and calcium, at energies below 1 keV. In
addition, we provide Sherman function values for elastic electron scattering
from calcium in the same energy range. This study extends the application of
our method of calculations, already employed for barium and strontium, to all
stable alkaline-earth-metal atoms. Our semi-empirical approach to treating
target polarization has produced in our earlier work a satisfactory agreement
with experimental values and precise theoretical results such as convergent
close-coupling calculations for barium. The present data are expected to be of
similar high accuracy, based on our previous success in similar calculations
for barium and all inert gases.
