Isotope Shift in the Muonic K X Rays of O16-O18, Ca40-Ca44, Sn116-Sn124, and Gd155-Gd160
Abstract
Measurements have been made of the isotope shift in the muonic K x rays for the pairs of isotopes O16-O18, Ca40-Ca44, Sn116-Sn124, and Gd155-Gd160. The measurements were limited in resolution by the conventional NaI detectors used: no fine or hyperfine structure was resolved. The results confirm the indications from optical isotope-shift measurements that the expansion in charge distribution of a nucleus on addition of neutrons is less than the expansion in the density distribution, and indicate that this trend is even more marked in the light nuclei examined.
