(a(i))[1]
State the complete nuclear notation for the $\alpha$-particle.
(a(ii))[1]
State the complete nuclear notation for the particle shown by the symbol $\Phi$.
(b(i))[2]
Calculate, for this reaction, the change in the total rest mass of the particles.
(b(ii))[2]
Calculate the energy, in joule, that is equivalent to the mass change found in (b)(i).
(c)[2]
Using your answer in (b)(i), comment on the energy of the $\alpha$-particle so that the reaction can occur.
