Abstract

It is shown that, if isospin is not conserved in a 00 -and f 0-meson mixing, forward-backward asymmetry arises in the pn→da 00 reaction. This effect increases near the reaction threshold. The asymmetry is estimated within the framework of a model in which the a 00 -f 0 mixing is due to the virtual π0↔η transition and the difference in masses of the charged and neutral kaons in decay channels. The angular asymmetry near the threshold of the pn→da 00 reaction was found to be large, of the order of 8–15%.
