Calculate the energy released (or energy input required) for the reaction
69-31Ga + n → α + 66-29Cu.
Q=
Energy released in above reaction will be given by:
Q = dm*c^2
Q = (m_Ga + m_n - m_alpha - mCu)*c^2
mn = mass of neutron = 1.008665 u
m_alpha = mass of alpha particle = 4.002602 u
m-Ga = mass of Galium = 69.723 u
m_Cu = mass of Copper = 63.546 u
(See that Check these values with your reference book for accurate answer, if any of these values are different than let me know in comments)
Using these values:
Q = (69.723 u + 1.008665 u - 4.002602 u - 63.546 u)*(931.5 MeV/u)
Q = 3.183063 u*(931.5 MeV/u)
Q = +2965.02318 MeV = Energy release from the above reaction
