The standard kinematic method for determining neutrino mass from the beta decay of tritium or other isotope is to measure the shape of the electron spectrum near the endpoint. It has been known for 30 years that a similar distortion of the "visible energy" remaining after electron capture is caused by neutrino mass. There has been a resurgence of interest in using this method with 163-Ho. Recent theoretical analyses offer reassurance that there are no significant theoretical uncertainties. We… 
The use of low temperature detectors for direct measurements of the mass of the electron neutrino
Recent years have witnessed many exciting breakthroughs in neutrino physics. The detection of neutrino oscillations has proved that neutrinos are massive particles, but the assessment of their
The calorimetric spectrum of the electron-capture decay of 163Ho. The spectral endpoint region
A bstractThe electron-neutrino mass (or masses and mixing angles) may be directly measurable in weak electron-capture decays. The favoured experimental technique is “calorimetric”. The optimal

Experimental Validation of Calorimetric Electron Capture Spectral Theory with $${}^{193}$$Pt
Using microcalorimeters, a high statistics, high-resolution calorimetric spectrum of electron capture in $${}^{163}$$ Ho can be used to determine the neutrino mass. The spectral shape can be
Ab initio calculation of the electron capture spectrum of 163Ho: Auger–Meitner decay into continuum states
Determining the electron neutrino mass by electron capture in 163Ho relies on an accurate understanding of the differential electron capture nuclear decay rate as a function of the distribution of
High-resolution and low-background $$^{163}$$Ho spectrum: interpretation of the resonance tails
The determination of the effective electron neutrino mass via kinematic analysis of beta and electron capture spectra is considered to be model-independent since it relies on energy and momentum

KATRIN plans to determine the electron anti-neutrino mass in the Tritium decay. Electron capture in 163Ho can measure the electron neutrino mass supported by the small decay energy Q = 2.8 keV 67 163
Electron capture and the neutrino mass
The electron neutrino mass can be determined by electron capture. One expects the largest influence of the neutrino mass on this decay for a small Q value of Q = 2.8 keV for 67163Ho+e→66163Dy+v. The
