Abstract:	We study a class of normalized special values of L-functions associated to elliptic curves (defined over Q) and real quadratic fields. Under certain hypotheses, we are able to show that these are squares of rational numbers. This result is used to improve upon a theorem of Bertolini-Darmon about a p-adic Gross-Zagier type formula.
