Abstract
We study the role of atomic collisions in future measurements of an in trinsic electric-dipole moment (EDM) of the electron using laser-coole d Cs atoms in an optical trap or in an atomic fountain. We find that t he shift in frequency and the line broadening caused by collisions may eventually limit the achievable sensitivity of these EDM experiments. We present the results of a coupled-channel calculation of these quan tities and discuss the symmetry aspects and magnetic-field dependences .
