A deuterium reaction that occurs in an experimental fusion reactor is in two stage: (a) Two deuterium (._1^2D) nuclei fuse together to form a tritium nucleus, with a proton as a by product written as D(D,p)T . (b) A tritium nucleus fuses with another deuterium nucleus to form a helium ._2^4He nucleus with neutron as a by - product, written as T (D,n) ._2^4He . Compute (a) the energy released in each of the two stages, (b) the energy released in the combined reaction per deutrium. (c ) What percentage of the mass energy of the initial deuterium is released. Given, {:(._1^2D=2.014102 am u),(._1^3 T=3.016049), (._2^4 He =4.002603 am u),(._1^1 H =1.007825 am u),(._0^1 n =1.00665 am u):} .
