Abstract
The G-parity irregular induced tensor form factor in the weak nucléon a×ial vector current has been precisely determined by measuring the alignment correlation terms in the βray angular distributions of the purely spin aligned mirror pair 12B and 12N, The coefficient of the induced tensor term was determined to be 2Mf TfA = -0.21 ±0.09 (stat.) ±0.07 (syst.) ± 0.05 (theory) at a 90% confidence level. The previously obtained data in the year 1996 was reanalyzed to be added to the present result. The combined result is 2MfTfA = -0.15 ± 0.12 ±0.05 (theory) at a 90% confidence level. The obtained induced tensor coefficient is vanishingly small. In order to derive these numerical values from the e×perimental data the weak magnetism and a×ial charge, and also their charge dependence should be known. Theoretical investigation on these quantities is clearly described. Also we set constraints on the Kubodera-Delorme-Rho parameters from the present result together with the results of correlation-type e×periments in the mass A = 8 and 20 systems as ς= -(0.12 ±0.14) × 10-3 MeV-1 and X = + (0.30 ±0.88) × 10-3 in the 1 σ level.
