摘要：

I point out that beta-delayed proton spectroscopy is a powerful probe of possible scalar contributions to nuclear beta decay, and use Schardt and Riisager's data on the shape of the beta-delayed proton peaks from the superallowed decays of 32Ar and 33Ar to set improved upper limits on such couplings. Implications of these limits for leptoquark masses are mentioned.
