(Note that the mass given differs from that which you provided by 1 electron mass.)
Furthermore, from http://atom.kaeri.re.kr/ton/nuc1.html you will see that the binding energy of Deuterium is 2224.573 +- 0.002 keV (i.e. 2.2 MeV). The binding energy is of course the energy release when the nucleus is created from free particles. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
