On the possibility of observation of $a_{0}$ - $f_{0}$ mixing in the $p n \to d a_{0}$ reaction

It is shown that, if isospin is not conserved in $a_{0}^{0}$ - and $f_{0}$ -meson mixing, forward-backward asymmetry arises in the reaction $p n \to d a_{0}^{0}$ . This effect increases near the reaction threshold. The asymmetry is estimated within the framework of a model in which the $a_{0}^{0}$ - $f_{0}$ mixing is due to the virtual $π^{0} \leftrightarrow η$ transition and the difference in masses of the charged and neutral kaons in decay channels. The angular asymmetry near the threshold of the $p n \to d a_{0}^{0}$ reaction was found to be large, of the order of $8 \div 15$ %.
