POLARIZATION EXPERIMENTS IN MIXED ALLOWED BETA-TRANSITIONS AS A CRITICAL TEST ON RIGHT-HANDED CURRENT HYPOTHESES

New crucial experiments are proposed for determining the parameters of the explicitly symmetric model of right-handed currents, i.e., the ex periments on measurement of the polarization of beta-electrons or gamm a-quanta in allowed mixed j-j transitions with j not-equal 0. These ex periments enable setting radically new restrictions on two parameters simultaneously, namely, the ratio of squared masses of two bosons and the mixing angle. These restrictions are similar in their nature to th ose imposed by experiments on the mu-enunuBAR decay, being free at the same time from the assumption about the mu-e universality.
