Abstract
The K-orbital electron capture in ions with one or two electrons is analized for a general allowed nuclear transition. For ionic hyperfine states the angular neutrino distribution and the electron capture rate are given in terms of nuclear matrix elements. A possible application towards the determination of neutrino parameters is outlined.
