Electron Capture and Beta-Decay RatesCollapse of O+Ne+Mg CoresTakahara et alWe present a new set of electron (e~-) capture and β-decay rates that improves previous calculations by Takahara et al. and Oda et al. by: (a) incorporation of recent charge-exchange and β-decay data, (b)...
In an investigation of A=146 isobars, produced in Ni bombardments of Mo, the electron capture and βdecay of the previously unknown isotope Er was identified. This nuclidic assignment was based on the observation of Ho K x rays in coincidence with β-delayed protons as well as in total-...
Electron capture beta decay of Be-7 located inside and outside the C-36 fullerene Equilibrium positions of the Be-7 atom both inside and outside the C-36 fullerene are found and the electron density at the Be-7 nucleus, rho(0), for these... Bodrenko,V I.,Avdeenkov,... 被引量:...
The periodic time modulations, found recently in the two-body orbital electron capture (EC) decay of both, hydrogen-like 140Pr58+ and 142Pm60+ ions, with periods near to 7s and amplitudes of about 20%, were re-investigated for the case of 142Pm60+ by using a 245MHz resonator cavity ...
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)...
Carrying out a first-principles calculation assuming linear relationship between the electron density at Be nucleus and the electron-capture (EC) decay rate, we explained why Be-Cshows higher EC decay rate than Be crystal, which was originally found experimentally by Ohtsuki et al. [Phys. Rev....
The possibility of influencing nuclear beta decay with high intensity, low frequency electromagnetic radiation (such as from a laser) is examined. The moti... I Blevis - University of British Columbia 被引量: 0发表: 1961年 Electrical Characteristics of a Pulsed Capillary Discharge The electrical ...
The electron capture decay of 85 Sr-measurements of the K X-Ray emission probability, half-life, and decay schemeThe K X-ray emission probability P K ω K for the decay of 85 Sr has been measured to be 0.5866 with a standard error of 0.05% and a systematic uncertainty of 0.65%. The...
The sum peak method has been applied to the electron capture probability changes for 133Ba when the transformation occurs in different compounds e.g. BaCl2, Ba(NO3)2, Ba-EDTA, and Ba-MES compounds.doi:10.1016/0883-2889(91)90204-EK.Singh...
Predominant electron-capture feeding in polonium-208 populates a 921 kev level in Bi208. The log ft. value of this transition was determined to be 13.7 in agreement with its assignment as a second forbidden transition Gamma-rays following electron-capture decay in polonium-208 were found at ...
