Imagine an atom made up of a proton and a hypothetical particle of double the mass of the electron but having the same charge as the electron. Apply the Bohr atom model and consider all possible transitions of this hypothetical particle to the first exited level . The longest wavelength photon that will be emitted has longest wavelength λ (given in terms of the Rydberg constant R for the hydrogen atom) equal to

electron makes transition from n=4 to n=1 level. Recoil momentum of the H atom will be In hydrogen atom
