Abstract

The absolute $H_{ρ}$ of the $K$ internal conversion electrons from the 2.6-Mev gamma-ray of ThD has been measured using a 180° magnetic spectrometer whose field was calibrated with the proton magnetic resonance. With a proton resonance frequency, $ν_{P}$ , of 3.75 megacycles, corresponding to a field of 880 gauss and an electron radius, $ρ$ , of 11.4 cm, the value $ν_{P ρ} = 42.528 \pm 0.008$ megacycle cm was obtained for the line. This is equivalent, through the proton gyromagnetic ratio, to an $H_{ρ} = 9988_{.4} \pm 2$ gauss cm.
