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-...
The EC decay process can be written symbolically (4.29)ZAX→ECZ−1 AX+v The captured electron comes from one of the inner orbitals of the atom. Depending on the electron shell from which the electron originates, the process is sometimes referred to as K-capture, L-capture,...

Electron capture10—the decay of unstable neutron-rich nuclides—converts a neutron into a proton by capturing an inner-shell −10e. Positron emission11 (beta-plus decay)—the decay of unstable proton-rich nuclides—converts a proton to a neutron in the nucleus coupled with the emission of...

In an investigation of [ital A]=146 isobars, produced in [sup 58]Ni bombardments of [sup 92]Mo, the electron capture and [beta][sup +] decay of the previously unknown isotope [sup 146]Er was identified. This nuclidic assignment was based on the observation of Ho [ital K] x rays ...
Two-neutrino double electron capture (2νECEC) is a second-order weak-interaction process with a predicted half-life that surpasses the age of the Universe by many orders of magnitude1. Until now, indications of 2νECEC decays have only been seen for two isotopes2,3,4,5, 78Kr and 130...
New supernova progenitor models incorporating modern electron capture and beta decay rates have recently become available. One of the more notable differences in these new models is an increase in the electron fraction throughout the iron core when compared to earlier models. We describe fully self...
If β+ decay is energetically possible, so also is electron capture, but the converse may not be true. For fixed A, the lowest energy isobar defines the valley of beta stability, (see Fig. 3). Because of the Coulomb energy, the heavier nuclei have N > Z. According to the ...
