Evans found that the series and the Pickering series can be obtained in a helium spectrum showing no trace of the ordinary hydrogen lines. These series were observed a few years a g o by Prof. Fowler by sending a heavy discharge through a m i x t x e of hydrogen and helium; previously they had been observed only in star spectra.   Niel Bohr’s Atomic Theory states that – an atom is like a planetary model where electrons were situated in discretely energized orbits. The atom would radiate a photon when an excited electron would jump down from a higher orbit to a lower orbit. The difference between the energies of those orbits would be equal to the energy of the photon. Furthermore, There were other lines that were known at the time in the infrared, the so-called Paschen series, and Bohr also applied to his model to helium-plus, where you change the value of z and now you get predictions of where the lines of helium-plus should be. If you wish to calculate the radius of the first Bohr orbit for some other hydrogen-like atom, such as $$\text{D}$$, or $$\text{He}^+$$, or muonic hydrogen, note that for such atoms the only things that are different are the masses or charges or both, so there is no need to repeat the tedious calculations that you have already done for hydrogen.
