33. If kinetic energy is not conserved, some of the neutron’s initial kinetic energy is used to excite the hydrogen atom. The least energy that the hydrogen atom can accept is the difference between the first excited state (n= 2) and the ground state (n= 1). Since the energy of a state with principal quantum number nis –(13.6 eV)/n2, the smallest excitation energy is
