In atomic absorption spectrometry, manganese vapour (Mn0 gas) with resonance absorption at 279.5 nm is heated to 2400 degrees Celsius in an air-acetylene flame. For every single atom in the first excited state, how many atoms exist in the ground state? Assume g1/ g0 = 1.
A beam of neutrons that all have the same energy scatters from atoms that have a spacing of 0.0910 nm in the surface plane of a crystal. The m = 1 intensity maximum occurs when the angle u in Fig. is 28.6°. What is the kinetic energy (in electron volts) of each neutron in the beam?
