The Nuclear Moments of Indium and Gallium

Q040curve is definite evidence of the presence of an ion of age equal to 0.04 seconds and mobility 13.1 cm/sec. per volt/cm. While this latter value is not exact owing to the lack of resolving power of the method under such conditions, particularly with the low current intensity obtained in hydrogen ionized by x-rays, the agreement with the value obtained by Loeb is extremely good in view of the uncertain temperature correction in his calculations. These experiments thus obtain a slightly more accurate absolute value for the mobility of the normal ion in hydrogen, and entirely substantiate the existence of one ion of much higher mobility as observed by Loeb. The detection of the 17.5 mobility ion is beyond the limits of this method. The experiments are being continued for ions in other gases. NORRIS BRADBURY
