  In the present work we examine the possibility of detecting light dark matter
particles (WIMP) utilizing their possible interactions with the electrons.
Employing reasonable theoretical models we evaluate the expected event rates in
the following cases: i) For WIMPs in the meV region treating electrons as free
and utilizing calorimetric detectors at low temperatures. ii) Detecting
recoiling electrons with energy in the eV region ejected out of an atom in the
case of WIMPs with a mass more than an order of magnitude heavier than the
electron. iii) By observing atomic excitations in the range of 1 meV to 10 eV
excitation energy induced by the electron spin interaction in a magnetic field.
