Abstract

The mass of ${Ne}^{20}$ measured from ten spectra is 19.9967±0.0009. This value is outside the limit of error of Aston's measurement and an explanation for his high mass value is suggested. The mass of $B^{11}$ was measured from two spectra as a test of the method used to determine the mass of ${Ne}^{22}$ . The mass of $B^{11}$ from these measurements is 11.0107±0.001. The mass of ${Ne}^{22}$ from five spectra is 21.9947±0.0009. The maximum value for the mass of ${Ne}^{22}$ is 21.9925±0.0015 calculated from Aston's value for $F^{19}$ and from the $F^{19}$ disintegration experiments of Chadwick and Constable. The discrepancy between the two values for the mass of ${Ne}^{22}$ is discussed.
