In a mixture of H-He^(+) gas ( He^(+) is singly ionized He atom), H atoms and He^(+) ions are excited to their respective first excited states. Subsequently, H atoms transfer their total excitation energy to He^(+) ions (by collisions). Assume that the Bohr model of atom is exctly valid. The ratio of the kinetic energy of the n=2 electron for the H atom to that of He^(+) ion is:
