摘要：

In order to clarify a long standing problem in mass spectroscopy we have carried out a careful reanalysis of our earlier work on the ratio of the Ar2+ to Ar+ partial ionization cross-section ratio using the pulsed-electron-beam time-of-flight method. Of all the possible error sources investigated only three were found to have a significant effect on the ratio but all three acted in the same direction. We have thus revised our previous estimates for the value of the ratio downward and increased our estimates of the uncertainy in our measurements. Our new results agree with those recently published in this journal as determined from a careful re-examination of the fast neutral beam technique.
