Laser-excited Rydberg atoms above a microwave waveguide …
WebA Rydberg atom is an excited atom with one or more electrons that have a very high principal quantum number, n. [1] [2] The higher the value of n, the farther the electron is from the nucleus, on average. Rydberg atoms have a number of peculiar properties including an exaggerated response to electric and magnetic fields, [3] long decay periods ... WebAbstract ：By using theoptical multichannel analyzer (OMA), this article will measure out the wavelength of ,,H H H αβγ in the Balmer series of hydrogen atomic spectrum, and work out the Rydberg constant of hydrogen atom by using the wavelength above.
