Abstract
Assuming a Yukawa potential, the minimum value of the dipole moment re quired to bind an electron in a medium is studied. The value of the mi nimum dipole moment is found to depend only on a dimensionless paramet er. A variational procedure with simple wave functions depending on on ly one parameter is used. For realistic screening, the results improve significantly the previously calculated values. [S0163-1829(98)05735- X].
