An alpha decay is the emission of an alpha particle (mass of 6.61 x 10-20 kg or 4 aum, atomic mass units) from an atomic nucleus. A Technetium mucleus (mass of 1.63 x 10-25 kg or 98 anu) undergoes an alpha decay, emitting a single alpha particle. Your detector catches the alpha particle and finds it velocity to be 1.5x 10 m/s What is the recoil velocity of the former Technetium (it's actually a Niobium now) nucleus? What is the final kinetic energy of the Niobium? What is the final kinetic energy of the alpha particle? What is the change in kinetic energy of this system? Where did the energy come from or go? What can you say about the unclear bond potential energy of the technetium atom compared to that of the niobium and alpha particle?
