Atomic and Nuclear Reactions

Lessons of Nuclear reactor physics by ing. Giorgio Bertucelli.

One exothermic reaction occurs when common aluminium is bombarded with high-energy a particles (He4) and is transmuted in Si30 a heavy isotope of silicon whose naturally occurring is Si28. In the reaction a small particle is emitted. Write the complete reaction and calculate the change in mass.

The reaction is

The particle emitted is a proton. Thus the complete reaction is

The isotope masses of the nuclei showing up in this reaction are:
