We calculate the rate for DsβββDsβΟ0 decay using Chiral
Perturbation Theory. This isospin violating process results from Ο0 -
Ξ· mixing, and its amplitude is proportional to (mdββmuβ)/(msββ(muβ+mdβ)/2). Experimental information on the branching
ratio for DsβββDsβΟ0 can provide insight into the pattern of
SU(3) violation in radiative Dβ decays.Comment: 7 pages with 2 figures not included but available upon request,
