Abstract

Results of an experiment to search for the metastable 2s state in muonic hydrogen at 150 and 600 Torr are presented. About 6% of all ωp formed go to the 2s state. Most of these (ωp)_{2 s} decay in less than 100 nsec; assuming a calculated lifetime of 2 ωsec at 150 Torr (0.5 ωsec at 600 Torr) for the long-lived fraction f of all 2s states, we find f to be less than 4% (16%) with 90% confidence level.

Measurement of the K X-ray intensity ratios in muonic hydrogen at low gas densities
1998, Physics Letters, Section A: General, Atomic and Solid State Physics
Measurements of the K X-ray transitions of muonic hydrogen (μ⁻p and μ⁻d) were performed at H₂ or D₂ gas pressures between 17 and 533 hPa (T ≈ 293 K). The intensity ratios $K_{α} K_{total}$ and $K_{β} K_{total}$ depend on the gas density because the strength of excited state collisional interactions increases at higher densities. The data are compared with the results of a cascade calculation. They are sensitive to the collisional Stark mixing rates at the main quantum levels n = 4, …,8.

Measurement of the K-line intensity ratios in muonic hydrogen between 0.25 and 150 torr gas pressures
1984, Physics Letters B
Precise measurements of the K X-ray energy spectrum of muonic hydrogen (μ⁻p) were made at H₂ gas pressures between 0.25 and 150 torr (T = 300 K). The measured intensity ratios $I(K_{α}) I(K_{tot})$ and $I (K_{β}) I(K_{γδ…})$ are compared with the results of new cascade calculations. The pressure dependence of the relative (μp)_2s population was investigated. Its value is (4.24 ± 0.14)% at 10 torr and (2.21 ± 0.22)% at 0.25 torr.
