WebThomson's measurement convinced him that cathode rays were particles, which were later identified as electrons, and he is generally credited with their discovery. The CODATA recommended value is −e/m e = −1.758 820 010 76 (53) × 10 11 C⋅kg −1. CODATA refers to this as the electron charge-to-mass quotient, but ratio is still commonly used. WebIn his second experiment, which came to be known as the J. J. Thomson experiment, he adjusted perpendicular B and fields so that the particles were undeflected at the ... EM-1 J. J.
