Frequency measurements of transitions from the $2^3{P}_2$ state to the $5^1{D}_2$, $5^3{S}_1$, and $5^{3}D$ states in ultracold helium

Jacob A. Ross, Kieran F. Thomas, Bryce M. Henson +4

We perform laser absorption spectroscopy with ultracold ${}^4$He atoms to measure the energy intervals between the $2^3{P}_2$ level and five levels in the n = 5 manifold. The lase…
