By using a phenomenological field theory of nucleon-nucleon interactions, Oberhummer et al. found a cross section of p+p --> d + e(+) + v(e) about 2.9 times that given by the potential approach and adopted in Standard Solar Model calculations. We show that a solar model with S = 2.9S(SSM) is inconsistent with helioseismic data, the difference between model predictions and helioseismic determinations being typically a factor ten larger than estimated uncertainties. We also show that, according to helioseismology, S cannot differ from S(SSM) by more than 15%. (C) 1998 Elsevier Science B.V.
