Rutherford, Ernst

In the discussion that followed, Rutherford added information about the work he was carrying on, in collaboration with Oliphant, on various reactions produced in lithium by bombardment with protons and deuterons,43 and Ernst Lawrence described in more detail the cyclotron he had invented and first constructed with a few collaborators in 1932.44... 

The subject of this book has it roots in chemistry and in nuclear science. Since every chemical element can be made radioactive and followed through chemical reactions by means of this property, radiochemistry has contributed to most areas of chemistry. Nuclear chemistry - according to a definition by Ernst Rutherford - includes all changes in elemental composition by nuclear reactions. 

Friedrich Ernst Dom in 1900. He used the same apparatus as Rutherford with thorium emanation and confirmed this. Using radium bromide he found a similar emanation, which did not penetrate aluminium as Rutherford (incorrectly) said thorium emanation did. Some doubts about the existence of radium emanation were removed by Rutherford and Soddy, who liquefied it by cooling in liquid air, and by Ramsay and Collie, who determined its spectrum. R. W. Gray and Ramsay determined its density by weighing on a microbalance and proposed for it the name m/on, shining . Actinium emanation was discovered by Debieme and by Giesel. The modem names thoron, radon, and actinon were proposed by W. Schmidt. ... 

The structure of the atom was revealed in 1911 as a result of Ernst Rutherford s interpretation of the 1909 Geiger-Marsden experiment (Rutherford 1911).
