Abstract
The matrix element \Vud of the CKM matrix can be determined by two independent measurements in neutron decay: the neutron lifetime and the ratio of coupling constants , which is most precisely determined by measurements of the beta asymmetry angular correlation coefficient~. We present recent progress on the determination of these coupling constants.
