71GA c 1991Ke05,1991Lj02: looked for a possible violation of the Pauli
71GA2c Exclusion Principle (PEP) in nuclear decays by trying to detect |g
71GA3c rays between 8 and 35 MeV with a 3.2 Curie {+71}Ge source and a
71GA4c well-type NaI(Tl) detector. If PEP is violated, it is expected
71GA5c that the excited states of {+71}Ga would be populated which would then
71GA6c decay by the emission of a |g ray or a nucleon. This probability was
71GA7c estimated in this work to be <3.0|*10{+-12} at a 95.5% confidence limit
71GA c 1991Zl01,1991Lj02: a search for neutrinos of mass 10-40 keV was made by
71GA2c analyzing the internal bremsstrahlung spectrum of {+71}Ge |e decay. The
71GA3c authors claim to have discovered evidence for a neutrino of
71GA4c mass=17.2 keV {I+13-11} (95% confidence limit) which is emitted in
71GA5c 1.6% {I8} (95% confidence limit) of the decays. In later works by
71GA6c 1993Di03 and 1995Le19, from the measurement of inner bremsstrahlung
71GA7c spectrum, no evidence was found for 17-keV neutrinos emitted by the
71GA8c decay of {+71}Ge
