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.
