Diamagnetic Structure of Na Rydberg States

Abstract

We present an experimental survey of a group of Rydberg states of sodium in magnetic fields up to 6 T, where levels from different terms overlap and interact strongly. The observed energy levels and relative line intensities for even-parity $m_l=1\mathrm{}$ terms in the vicinity $n=28\mathrm{}$ are in good agreement with calculations based on a numerical diagonalization using spherical basis states in the range $n=25-31\mathrm{}$.
