2.7 Two H-atoms collide head-on. After the collision, the net KE of both atoms is zero. Each atom
then emits a photon of wavelength = 121.6 nm, due to a (n 2) → (n 1) electron
transition. The rest mass of an H-atom is 1.673 × 10-27 kg. At what speed were the two
atoms moving before the collision? Were relativistic correction necessary in the calculation of
the speed?

- The Bohr model correctly predicts the main energy levels not only for atomic hydrogen but also for other "one-electron" atoms where all but one of the atomic electrons has been removed, such as in He+ (one electron removed) or Li++ (two electrons removed). The negative muon (μ−)behaves like a heavy electron, with the same charge as the electron but with a mass 207 times as large as the electron mass. As a moving μ− comes to rest in matter, it tends to knock electrons out of atoms and settle down onto a nucleus to form a "one-muon" atom. For a system consisting of a nucleus of iridium (Ir192 with 77 protons and 115 neutrons) and just one negative muon, predict the energy in eV of a photon emitted in a transition from the first excited state to the ground state. The high-energy photons emitted by transitions between energy levels in such "muonic atoms" are easily observed in experiments with muons.arrow_forwarda) Study the splitting of the second and the third excited states of the H-atom due to the relativistic correction of the kinetic energy of electron (ignore the spin of the electron).
