The antiprotonic x-ray spectrum of liquid helium

The X-ray spectrum of liquid p̄-He has been measured. The energies and relative intensities of the X-ray transitions feeding the 3d and 2p levels were determined. The analysis of the L series yielded a strong interaction shift ε and width Γ for the 2p level of ϵ 2p = (−50 ± 18) eV and Γ 2p = (90 ± 7...

Summary:The X-ray spectrum of liquid p̄-He has been measured. The energies and relative intensities of the X-ray transitions feeding the 3d and 2p levels were determined. The analysis of the L series yielded a strong interaction shift ε and width Γ for the 2p level of ϵ 2p = (−50 ± 18) eV and Γ 2p = (90 ± 70) eV.
