Electron-capture branch of Tc-100 and tests of nuclear wave functions for double-beta decays Academic Article uri icon


  • We present a measurement of the electron-capture branch of Tc100. Our value, B(EC)=(2.60.4)10-5, implies that the Mo100 neutrino absorption cross section to the ground state of Tc100 is roughly 50% larger than previously thought. Disagreement between the experimental value and QRPA calculations relevant to double- decay matrix elements persists. We find agreement with previous measurements of the 539.5- and 590.8-keV -ray intensities. 2008 The American Physical Society.
