Calorimeter Experiment (No Neutrino)
Calorimeter Experiment (No Neutrino)

Introduction:
A considerable number of researches with cloud chambers have reported that the en-ergy lost in the scattering of beta-rays by heavy nuclei is several times the radiation loss calculated from the well-established Bethe-Heitler theory. For example, Klarmann and Bothe[2] report that in the energy range from 0.5 to 2.4 Mev the
inelastic scat-tering in krypton and xenon is 2 to 5 times that predicted by the theory. Leprince-Ringuet[3] found indications of 10 times the expected amount for argon in the range 1 to 3 Mev and Laslett and Hurst[4] observed that, for lead, the scattering is high by a fac-tor of 30 for energies from 1.5 to 4.5 Mew. Barber and Champion[5] found 6 times too much inelastic scattering for 1-Mev elec-trons scattered by mercury. It does not ap-pear that theses excess energy losses can be due to the production of x-rays as Arci-movic and Chramov[6] and Petrauskas, Van Atta, and Myers[7] have found experimen-tally that the production of x-rays in this en-ergy range is in agreement with the theory. To account for the large extra energy losses, which have been reported, Klar mann and Bothe, and Champion[8] have suggested the emission of neutrinos as well as x-rays resulting from the interaction of fast electrons with heavy nuclei. In the case of the continuous beta-ray spectrum, calo-rimeter experiments performed by Ellis and Wooster[9] and by Meitner and Orth-mann[10] have been employed to investi-gate the energy losses due to neutrino emission. The purpose of the calorimeter experiment described here was to deter-mine whether or not the large energy losses referred to above could be accounted for by the emission of neutrinos or other ex-tremely penetrating radiation.[11] […]
