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......
Electron-capture decayNuclear structureBoth 100Mo and 116Cd are zero-neutrino double-尾-decay candidates with J 蟺 = 0 + and the ground states of the respective intermediate nuclei, 100Tc and 116In, have J 蟺 = 1 + . This makes it possible to measure these matrix elements, which turn ...

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....
Mention has been made of the electron capture decay process whereby an electron from one of the atomic shells (generally the innermost K shell) is absorbed by the nucleus, where it combines with a proton to form a neutron. No particle emission results from this decay process. However, the ...

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)...
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-...
With the use of an on-line mass separator, electron capture (EC) and ${mathrm{$beta${}}}^{+}$ decay of the direct proton emitter $^{147}mathrm{Tm}$ was identified in a series of $^{58}mathrm{Ni}$${+}^{92}$Mo irradiations. Characteristic Er K$alpha${} x rays and an 80.9...
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 ...
