Hyperfine structure and isotope shift of the D/sub 2/ line of /sup 118-145/Cs and some of their isomers

High-resolution laser spectroscopy has been performed on /sup 118-145 /Cs and /sup 119m,121m,122m,130m,134m,135m,136m,138m/Cs. The Cs nuclei have been produced either by spallation of La or by fission of U by the 600 MeV proton beam, from the SC at CERN. The hyperfine structures, spins, and isotope...

Sumario:High-resolution laser spectroscopy has been performed on /sup 118-145 /Cs and /sup 119m,121m,122m,130m,134m,135m,136m,138m/Cs. The Cs nuclei have been produced either by spallation of La or by fission of U by the 600 MeV proton beam, from the SC at CERN. The hyperfine structures, spins, and isotope shifts have been measured. The charge radii changes deduced from the isotope shifts exhibit shell effects at N=82, isomeric staggering for N=64,66,67 and a strong odd-even staggering for all isotopes with N<82. (24 refs).
