Hyperfine structure and nuclear magnetic moments of the praseodymium isotopes135,136,137Pr

CollinearLaser spectroscopy was applied to measure the hyperfine structureof 135 − 137Pr at ISOLDE/CERN. Combined with measurements of the stable isotope 141Pr at the TRIGA- SPECsetup in Mainz we were able to determine the magnetic momentsof the neutron-deficient isotopes 135Pr, 136Pr and 137Pr for the first time.
