Semiconductor Detectors and Double Beta Decay

摘要: Theoretical physicists have devoted great effort to developing an adequate theory for linking the weak, electromagnetic, and strong forces of nature. Recent theoretical studies observations stability galaxies strongly indicated presence large amounts invisible mass. One element in uncertainty associated with missing mass is question whether neutrino has rest A better understanding neutrino, explored this paper by possibility double beta decay germanium 76 isotope, could perhaps provide some answers. Nuclear transitions are only energetically possible where final nucleus more tightly bound than its parent. The arsenic not because isotope about 0.9 MeV less germanium. selenium on other hand, 2 bound; therefore, a transition involving emission two electrons form possible. total energy release kinetic particles corresponding neutrinos from excited daughter product determined difference.
