Measurement of thes-wave contribution to 2p-level shifts in pionic atoms

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

Energies and widths of pionic 3d-2p transitions of30Zn,32Ge, and33As have been measured with a Ge detector. The values of the 2p shifts obtained from the measurementε 2p (Zn)=7.0±1.4keV,ε 2p (Ge)=5.5±0.9keV, andε 2p (As)=4.6±0.9keV show a decreasing behaviour for largeZ, which is caused by an increasings-wave contribution as predicted by theory.
