- Abstract
It is shown that, if isospin is not conserved in a[sub 0][sup 0] - and f[sub 0]-meson mixing, forward–backward asymmetry arises in the pn→[sub ]da[sub 0][sup 0] reaction. This effect increases near the reaction threshold. The asymmetry is estimated within the framework of a model in which the a[sub 0][sup 0]–f[sub 0] mixing is due to the virtual π[sup 0]↔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→[sub ]da[sub 0][sup 0] reaction was found to be large, of the order of 8–15%. © 2000 MAIK “Nauka / Interperiodica”.
