Unformatted text preview: paper (W. Bleakney, Phys. Rev., 1929 , 34, 157) but the schematic and x-axis on Fig. 4 should give it way. Q3. How are the ions generated in the source of this mass spectrometer? Q4. The method of generating ions in this device was a modification of a procedure discovered by A.J. Dempster. ( Phys. Rev. , 1917 , 11(4), p.316). In this report Dempster derived a merit of resolving power which is similar to what we use today. What was the resolution calculated by Dempster for the H 2 + ion? Q5. Why does the peak corresponding to the N14N15 + ion come out at a lower potential than the one from the N14N14 + ion? Based on equation 1 in the Nitrogen Isotopes paper, what is the field strength of the magnet?...
