Question: Show that some of the "Balmer-series" lines of singly ionized helium are the same as lines of the hydrogen Lyman series. Which ones are they, in general? This correspondence was a source of confusion when spectral lines of He ions were first observed in the solar spectrum; some people speculated that they were seeing a new form of hydrogen not found on Earth.
