Abstract

We calculate the combined angular distributions of the photon and the electron in the cascade process pp-;J(e+e-) (J=2,1,0), in terms of the helicity or the multipole transition amplitudes in. Our expressions for them differ from those found previously. We describe the origin of these differences. The effect of the motion of in the J rest frame on the angular-distribution functions is taken into account.
