The gamma-ray, X-ray and conversion-electron data from singles and coincidence measurements confirmed the known level scheme of 231 Pa. Almost all of the vacancies in the atomic K shell are produced by electron capture in the decay of 231 U. Thus, the relative K X-ray intensities can be...

Measurement of the beta(+) and orbital electron-capture decay rates in fully ionized, hydrogenlike, and heliumlike (140)Pr ions We report on the first measurement of the 灏 + and orbital electron-capture decay rates of 140Pr nuclei with the simplest electron configurations: bare nucl......
Energy Spectrum of Atomic Electrons Ejected in Electron-Capture Decay of Fe55 The shape of the energy spectrum of orbital electrons ejected from Feduring nuclear decay by electron capture has been measured from 28 to 190 keV (the the... JG Pengra,B Crasemann - 《Physical Review》 被引量: ...
"experimentalAtomicShellElectronCaptureFractions" An array type containing the experimentally-measured fraction of decay by electron capture for the atomic subshells. "selectionRulesDeltaJ" A number type (integer) corresponding to the difference in spin values between initial and final states associated wi...
As mentioned in Chapter 2, radionuclides decay by α-, β −- and β +-particle emission, electron capture, or isomeric transition. The radioactive decay is a random process, and it is not possible to tell which atom from a...
A new measurement has been made of the electron capture to positron branching ratio in the decay of Na to the 1.27 MeV level in Ne. The value of 0.1077 +-0.0006 obtained is about 3% larger than other precise values and is compared with recent theoretical estimates. (author)...
