The carbon isotope ¹²₆C has a nuclear mass of 12·000000 u. Calculate the binding energy of its nucleus. Given mp = 1·007825 u; mn = 1·008665 u.
What is meant by ionisation energy? Write its value for hydrogen atom.
Define the term, mass defect. How is it related to stability of the nucleus?
Calculate the energy released in MeV in the following reaction: ²₁H + ³₁H → ⁴₂He + n Given: m(²₁H) = 2.014102 u m(³₁H) = 3.016049 u m(⁴₂He) = 4.002603 u mₙ = 1.008665 u
Imagine the fission of a ⁵⁶₂₆Fe into two equal fragments of ²⁸₁₃Al nucleus. Is the fission energetically possible? Justify your answer by working out Q value of the process. Given: m(⁵⁶₂₆Fe) = 55·93494 u, m(²⁸₁₃Al) = 27·98191 u.
In a fission event of ²³⁸₉₂U by fast moving neutrons, no neutrons are emitted and final products, after the beta decay of the primary fragments, are ¹⁴⁰₅₈Ce and ⁹⁹₄₄Ru. Calculate Q for this process. Neglect the masses of electrons/positrons emitted during the intermediate steps.
