Isospin breaking in scalar and pseudoscalar channels of radiative -decays
In the framework of simple assumption on factorizing a mixing of vector state
with isoscalar components in effective amplitudes of isospin breaking caused by
the electromagnetic quark current, a branching fraction of radiative transition is evaluated at the level of .Comment: 3 pages, revtex4 class, 2 eps-figures; reference, comment and
