Description

We have measured np→dπ0 cross sections at ten beam energies within 16 MeV of threshold. Total cross sections followed closely the relationship σtot(np→dπ0) = (1/2)[(184±5)η3]μb, where η is the c.m. pion momentum in units of mπc. The differential cross sections are anisotropic at only 1 MeV (c.m.) above threshold. These results are predicted by Faddeev model calculations and by a perturbative model. Our cross sections are in fair agreement with previous π+d→pp data. (Author) 12 refs., tab., 4 figs
