Abstract :
Recently, Dolgov and Smirnov speculated that neutrinos may not obey the principle named after their inventor, the Pauli Principle. The neutrino wave function may contain a bosonic component. In principle, two-neutrino double-beta (image) decay data could be used to check on the conjecture that neutrinos violate the Pauli Principle. Recent image data on 100Mo to both the ground state and excited states in 100Ru will be used to illustrate the procedure.
