For 816O, p = 8 and n = 8

8p = 8X1.007276 = 8.058208
8n = 8X1.008665 = 8.069320
8e = 8X0.000549 = 0.004392
Total = 16.131920 amu
The mass of the neutral atom is (from table p21-8) 15.994915 amu
Difference = 0.137005 amu X 931.48 MeV/amu = 128 MeV

For 919F, p = 9 and n = 10

9p = 9X1.007276 = 9.065484
10n = 10X1.008665 = 10.086650
9e = 9X0.000549 = 0.004941
Total = 18.157075 amu
The mass of the neutral atom is (from table p21-8) 18.998403 amu
Difference = 0.158672 amu X 931.48 MeV/amu = 148 MeV
