- Abstract
- The presence of a scalar interaction in nuclear beta-decay was studied by measuring the beta-neutrino correlation coefficient alpha in the superallowed pure Fermi beta-transition Ne-18(O+) --> F-18(O+, 1040 keV) (T-1/2 = 1.67 s). The resulting value, i.e. alpha = + 1.06 +/- 0.19 (error quoted at 2 sigma), corresponds to the limit root/C-s/(2) + C-s'(2) less than or equal to 0.29C-v (95%) CL for the scalar coupling constant.
