Abstract
A complete and improved calculation of phase space factors (PSF) for and decay, as well as for the competing modes , , and , is presented. The calculation makes use of exact Dirac wave functions with finite nuclear size and electron screening and includes life-times, single and summed positron spectra, and angular positron correlations.
