✦ Synopsis

A re-analysis of J p ¼ 0 þ -0 þ super-allowed Fermi transitions, following Wilkinson (Nucl. Instr. and Meth. A 488 (2002) 654), using further input and a more-detailed procedure yields jV ud j 2 ¼ 0:950070:0009; jV ud j 2 þ jV us j 2 þ jV ub j 2 ¼ 0:998270:0015 or jV ud j 2 þ jV us j 2 þ jV ub j 2 ¼ 0:999370:0013 with the operational vector coupling constant G Ã V =ð_cÞ 3 ¼ ð1:1505070:00027Þ Â 10 À5 GeV À2 :
