THE OXIDATION OF HYDRAZINE. V. REACTION BETWEEN POTASSIUM IODATE AND HYDRAZINE SULFATE.¹

Abstract

I353 an alpha particle which captured an electron before it reached the cathode would have a value e/m = a g x ICP. This value was actually determined for the particles which produced patch c. There still remains the probability that a considerable number of alpha particles would combine with two electrons and form neutral helium atoms before reaching the cathode, and these would be undefleeted in the space back of the cathode and would form the central bright patch. On the whole, then, it seems established within the limits of error,of the experiment that alpha particles were given off from the anode and formed an important part of the Kanalstrahlm. This explanation will also account for the sometimes unaccountable appearance of helium in vacuum tubes through which an electric charge has been passed. A striking example of this is given by Soddy in Proc. Roy. Soc., London (A) , 80, 94, and while the explanation which he there oiTers may be the correct one it seems not impossible that the one here suggested may be the true one, instead.
