Suppose a moving hydrogen atom makes a head on inelastic collision with a stationary hydrogen atom. Before collision, both atoms are ground state and after collision, they move together. What is the minimum velocity of the moving hydrogen atom if one of the atoms is to be given the minimum excitation energy after the collisions? Take m_H=1.0078 am u. 1.66xx10^(-27)kg.

An electron colliodes with a hydrogen atom in its ground state and excites it to n=3 state . The energy given to the hydrogen atom in this inelastic collision ( neglecting the recoil of hydrogen atom ) is

A moving H-atom makes a head on perfectly inelastic collision with a stationary Li^(++) ion. Just before collision, both - H and Li^(++) are in their first excited state. Immediately after collision H was found to be in ground state and Li^(++) was in its second excited state. Find the kinetic energy of H – atom before collision. No photon is emitted in the process. Assume that mass of Li^(++) is nearly 7 times the mass of H.

An hydrogen atom moves with a velocity u and makes a head on inelastic collision with another stationary H-atom. Both atoms are in ground state before collision. The minimum value of u if one of them is to be given a minimum excitation energy is

Suppose a moving hydrogen atmo makes a head on inelastic collision with a stationary hydrogen atmo. Before collision both atoms are in ground state and after collision they move together. What is the minimum velocity of the moving hydrogen atom if one of the atom is to be given the minimum excitation energy after the collision ? (m_(H) = 1.0078 am u, 1 am u = 1.66 xx 10^(-27) kg)
