Abstract

The sensitivity of observables in radiative decays \ensuremathψ(2S)\ensuremath→\ensuremathγ\ensuremathχ_c1,2\ensuremath→\ensuremathγ\ensuremathγJ/\ensuremathψ to quadrupole (M2) admixtures in the dominant electric dipole (E1) transitions is explored. Emphasis is placed on distributions in a single angle, and several examples are given.
