IN an earlier paper1, I have shown that sodium and phosphorus become radioactive under bombardment with alpha rays, presumably corresponding to the creation of Al26 and Cl34 respectively. In the case of phosphorus, chemical separation of the active body, kindly carried out by Prof. S. Sugden, gave strong support to this picture. Between these two unstable isotopes lies a third one, P30, found by Curie and Joliot2. It was pointed out that another link of that chain, Na22, should be produced by…

The discovery by Rutherford in 1919 that $$\alpha$$-particles could induce nuclear reactions and transform isotopes and elements opened up the possibility to produce new isotopes in the laboratory.

R. R. Frisch brought to physics the approach of a craftsman, not only in his love for music and his skill and taste as a pianist and a violinist, but in the use of language, which made him an outstanding expositor.

The latest experiments have shown a very striking fact: when an aluminium foil is irradiated on a polonium preparation, the emission of positrons does not cease immediately, when the active preparation is removed, as for an ordinary radio-element.
