Recent Determination of the Atomic Masses of H, D, 35Cl and 37Cl at Osaka University
At the days of the Winnipeg Conference in 1967, we had some difficulties in the focussing characteristics of our reconstructed large mass spectrograph. The cause of the difficulties had not been found out as long as the machine was operated under the graphic mode. In changing from graphic to metric, it became clear that the main cause of this difficulty was the stray a.c. magnetic field filling in the room 1). Since then, we have been operating the machine in the mass-spectrometric mode, and for the measurement of doublet mass differences the peak-matching techniques have been adopted.
