Abstracts
The simple theory of electron capture is outlined and three methods for its detection are suggested. The first experimental evidence for the process (in activated titanium) is described. A rigorous experimental proof of the hypothesis is given for the case of ⁶⁷Ga. A summary of several isotopes whose properties are best explained on this hypothesis is appended. The properties of ⁶⁷Ga are described in considerable detail, and include the first evidence for internal conversion in artificially radioactive atoms.
