M2 signatures in {psi}(2S) radiative decays

The sensitivity of observables in radiative decays {psi}(2S){yields}{gamma}{chi}{sub c1,2}{yields}{gamma}{gamma}J/{psi} 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.
