Radiative transitions of the D states of charmonium in potential models

We derive expressions for the radiative multipole amplitudes and the total decay rates of heavy quarkonia in the transitions 13D2→13PJ+γ (J=2,1,0), 13D2→n1S0+γ (n=1,2), 11D2→11P1+γ, 11D2→n3S1+γ (n=1,2), and 13D1→13PJ+γ (J=2,1,0), in an arbitrary potential model correct to order v2/c2. We also numerically evaluate these expressions for charmonium in the nonsingular potential model of Gupta, Johnson, Repko, and Suchyta. copyright 1997 The American Physical Society
