Problem

The reaction

^2_1\mathrm D + ^3_1\mathrm T \rightarrow ^4_2\mathrm{He} + n

occurs in certain fusion reactors. The atomic masses are

^2_1\mathrm D = 2.014102\,\text{u}

^3_1\mathrm T = 3.016049\,\text{u}

^4_2\mathrm{He} = 4.002603\,\text{u}

n = 1.008665\,\text{u}

. (a) Calculate the energy released in the reaction. (b) What fraction of the initial mass is converted into energy? (Use

1\,\text{u} = 931\,\text{MeV}/c^{2}

.) a. (a) Energy released b. (b) Fraction of initial mass converted
