Abstract
IN the course of Lord Rutherford's Friday evening discourse on March 23 at the Royal Institution (see p. 481), experiments were shown to illustrate the differences in freezing point and in vapour pressure between ordinary and heavy water, and the differences in heat conductivity between ordinary and heavy hydrogen. For the first time, experiments were made to show the artificial transformation of lithium by protons and diplons of energy corresponding to about 100,000 volts. The enormous emission of fast protons when ammonium sulphate containing heavy hydrogen was bombarded by diplons was clearly shown by counting methods. The transformation apparatus was designed and operated by Dr. Oliphant, while Messrs. Watson and Sons (Electro-Medical) Ltd. loaned an installation to provide a steady potential of 100,000 volts to accelerate the ions.
