  We have studied the angular time delay in slow-electron elastic scattering by
spherical targets as well as the average time delay of electrons in this
process. It is demonstrated how the angular time delay is connected to the
Eisenbud-Wigner-Smith (EWS) time delay. The specific features of both angular
and energy dependences of these time delays are discussed in detail. The
potentialities of the derived general formulas are illustrated by the numerical
calculations of the time delays of slow electrons in the potential fields of
both absolutely hard sphere and delta-shell potential well of the same radius.
The studies conducted shed more light on the specific features of these time
delays.
