Calculate the Q - value for the reaction , `""_(1)H^(2)(d,n)_(2)He^3`

Text Solution

Verified by Experts

The nuclear reaction given to us is
`""_1H^2+""_1H^2rarr""_2He^(3)+""_(0)n^(1)+Q`
`Q=[2m(""_(1)H^2)-m(""_(2)He^(3))-m(""_(0)n^(1))].c^2`
`= [2xx2.014 - 3.0163 - 1.00867] "a.m.u" xx ` 931 MeV/a.m.u
`~= 3.19 MeV.`
