Consider a head on collision between a neutron moving with speed v (KE = 24.5 eV) and a-H-atom initially at rest. Now analyze the KEs of these particles after collision for the cases :
(i) If collision is perfectly elastic
(ii) Collision is inelastic and H-atom is excited to first excited state.
(iii) Collision is inelastic and H-atom is excited to second excited state.
Also write equations to find their speeds after collision.
