Abstract
For the first time the electron capture and beta(+) decay rates of H-like Pr-140 ions have been measured at the FRS-ESR facility by using the Schottky noise technique. The H-like Pr-140(58+) decay rate was found to be larger by a factor of 1.5 than in the case of neutral atom. This non-intuitive result can be explained by taking into account hyperfine splitting of nuclear levels in the decaying nuclei and the conservation law of the total angular momentum of the system.File in questo prodotto:
