a) By applying the laws of conservation of energy and momentum, show that the K.E of αparticle radiated (during α-decay) is given by. T α = Q(A − 4) A ; where Q represents the energy available in the decay and A, the mass of the parent nucleus.
(b) Show that 236 94 P u is unstable and will spontaneously decay into 232 92 U. Consider: 236 94 P u = 236.046071u; 232 92 U = 232.037168u; 4 2He = 4.012603u.
