摘要：

The nuclear K-shell electron-capture (EC) and positron (beta(+)) decay constants, lambda(EC) and lambda(beta+) of H-like Pr-140(58+) and He-like Pr-140(57+) ions, measured recently in the experimental storage ring (ESR) at GSI, were calculated using standard weak interaction theory. The calculated ratios R = lambda(EC)/lambda(beta+) of the decay constants agree with the experimental values within an accuracy better than 3%.
