The conversion spectrum of 83mKr has been measured to a precision of 25 eV. Conclusive observation of the K , L, M , and N series electrons demonstrates the range and generality of the technique. Future upgrades to the prototype are suggested, with an outlook toward a detector resolution of 1 eV.application/pdfen-USCopyright is held by the individual authors.Neutrino; RadiofrequencyNuclear physicsParticle physicsphysicsThesis
