μ-Atomic Lyman and Balmer Series in Ti, TiO2. and Mn

Abstract

$\mu$-atomic Lyman and Balmer series were observed in Ti, Ti${\mathrm{O}}_2$, and Mn using a large high-resolution Ge(Li) detector. While the relative line intensities are, for the most part, accounted for reasonably well by a cascade model, systematic differences were found in comparing the intensities in Ti${\mathrm{O}}_2$ and Ti. The $2p-2s$ splitting was observed for the first time in muonic atoms.
