The Beta-Spectrum of S³⁵

ECENTLY Cook, Langer, ' and Prices have published results on S" negatrons and both positrons and negatrons from Cu~ which show an increase in number over that predicted by the Fermi theory at low energies. Because it is difficult to understand theoretically why such
deviations should occur at low energy after the Coulomb correction has been made, an attempt was made to check these results with thinner sources.
