摘要：

The relative polarization of positrons emitted in pure Fermi (O-14) and Gamow-Teller (C-10) decays has been measured using a new technique based on time-resolved positronium decay. The result P(GT/P(F) = 0.9996 +/- 0.0037 provides constraints on possible right-handed and scalar-tensor current admixtures to the weak interaction of -4 < zeta-delta x 10(4) < 7 and [(C(S)/C(V)) - (C(T)/C(A))[ = (1 +/- 9) x 10(-3) (90% C.L.), respectively.
