An Attempt to Add an Electron to the Nucleus of an Atom

摘要: Since the present theories of atom indicate that an electron is attracted by nucleus, they also suggest principal difficulty in accomplishing addition obtaining such (unknown) conditions as make attraction effective. Electrons with a velocity corresponding to 138,000 145,000 volts were caused strike surface liquid mercury. The mercury served anti-cathode x-ray tube. (This work was done before tube Coolidge available.) When experiments begun it not expected positive results would be attained, since either voltage may too low, or number electrons shot into (4\ifmmode\times\else\texttimes\fi{}${10}^{21}$) small, but thought value show this true. nucleus should give gold. no gold found exceedingly sensitive tests used, shown less than one billion attached itself else all part nuclei produced sufficiently stable endure for period (24 48 hours) tests.
