1928 H. D. Hubbard Explanatory Key to Periodic Chart of Atoms 20 The positive atom of electricity, the ‘proton’ is 1845 times heavier than the negative.

1938 Encycl. Brit. Bk. of Year 404/1 The prediction of the possibility under certain conditions of the materialization of radiation quanta into a positon and a negaton.
1955 O. Klein in W. Pauli Niels Bohr & Devel. Physics 115 Assuming..that there are no negaton-positon interaction terms.
