| dc.description.abstract | The pionic 2p-ls transition was observed in the isotope pair ¹⁶, ¹⁸0. The 2p-ls X-ray energies and Lorentzian widths were measured, and the hadronic and isotope shifts were calculated. The results were: E (keV) ¹⁶0 160.286 ¹⁸0 155.792 Isotope Effect ( 19a _ 16a) (. 090) (.160) ε:(keV) -15.13 (.13) -19.63 (.20) -4.50 (.24) Γ(keV) 7.32 (.30) 5.97 (.59) -1.35 ( .66) Comparison of the results with other experiments and theory shows good agreement for the isotope shifts and Lorentzian widths, but shows a systematic discrepancy between the present transition energies and other recent results. The discrepancy may be due to the use of different lineshape fitting functions in the two analyses. The experimental spectra also yielded measurements of the pionic 3d-2p X-ray energies and Lorentzian widths, and the muonic np-ls X-ray energies, up to n=5. The results were in agreement with other experiments. | |
