Why Is the Isoscalar rho Exchange Contribution to the Circular Polarization in N + p Implies D + gamma Almost Zero

摘要

It is shown that the smallness of the contribution of the isoscalar part of the parity violating rho exchange potential to the circular polarisation of the photon emitted in the reaction n + p implies d + gamma is a consequence of the low energy peak of the E1 excitation spectrum of the deuteron.
