Abstract
A first-principles calculation of the field gradient due to conduction electrons in Be leads to a contribution opposite in sign to that from ionic charges, in agreement with expectations from experiment. This result is of particular interest for the theory of nuclear quadrupole coupling constants in metals in view of recent experimental determinations of the sign of the latter.Keywords
