Nuclear Structure: calculation of the asymmetry α∓ of β rays emitted from polarized12B and12N nuclei. Comparison with experimental values. Formulae for the asymmetry parameters α∓ of β rays emitted from polarized nuclei is derived using the formalism developed by Behrens-Bühring. The induced interactions are studied in detail. It is demonstrated that the expressions for α∓ are independent of the induced pseudoscalar interaction. It was found that the corrections to the lowest order approximation are small. Experimental data of the Louvain and Osaka laboratories are analyzed. We should point out that the data of the asymmetry of the β- decay of12B obtained in these two laboratories are quite different. Although the data reported by the Osaka Group require the existence of the induced pseudotensor (IPT) interaction as it has also been stated by other authors, if we combine data of12N from Osaka and of12B from Lauvain such experimental results can be understood without including the IPT interaction. Thus, we found some evidence that the IPT interaction could be not necessary to explain the asymmetries in the decay of members of the A=12 system. © 1978 Springer-Verlag. Fil:Szybisz, L.
