Mn. Butler et al., ERRATUM AND ADDENDUM TO E2 M1 MIXING-RATIO OF DELTA-]N-GAMMA AND HYPERON RESONANCE RADIATIVE DECAY/, Physics letters. Section B, 314(1), 1993, pp. 122-124
We correct an error in the definition of our amplitudes, and then disc
uss using gamma-gamma correlations to find the ratio of electric quadr
upole to magnetic dipole transitions in the electromagnetic production
and decay of the DELTA.
