Laser spectroscopy of two 2S-2P transitions in μp was used to determine both the Lamb shift and the hyperfine splitting of the 2S state in μp. The rms charge radius of the proton, inline image fm, was extracted from the Lamb shift. The Zemach radius of the proton, Rz = 1.082(37) fm, was obtained from the 2S-hyperfine splitting. This article summarizes the previously published findings. application/pdf https://folia.unifr.ch/global/documents/303093 https://folia.unifr.ch/documents/303093/files/kno_lsm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1002/andp.201300058 info:eu-repo/semantics/openAccess License undefined Annalen der Physik. - 2013, p. – Muonic hydrogen Proton radius Charge radius Zemach radius Rydberg constant Proton radius puzzle info:eu-repo/classification/udc/53 Laser spectroscopy of muonic hydrogen http://purl.org/coar/resource_type/c_6501
