Description
Precision measurements in the H atom play an important role in atomic physics and are used to determine the Rydberg constant R∞ and the proton charge radius rp. In 2010, measurements in muonic hydrogen indicated that the values of R∞ and rp determined from H-atom spectroscopy at low principal quantum number (n < 13) might be in error by several standard deviations, a discrepancy known as the proton-size puzzle. To resolve this puzzle, I determined during my dissertation an independent value of R∞ from measurements of transitions to states of the H atom with n> 20.
