Magnetic dipole moments near Sn-132: new measurement on I-135 by NMR/ON

On-line low temperature nuclear orientation (OLNO) experiments have been performed on the isotope 135I using the technique of nuclear magnetic resonance on oriented nuclei (NMR/ON). The magnetic moment of the 7/2+ ground state has been measured to be μ(7/2+135I) = 2.940(2)μN, thereby extending the k...

description On-line low temperature nuclear orientation (OLNO) experiments have been performed on the isotope 135I using the technique of nuclear magnetic resonance on oriented nuclei (NMR/ON). The magnetic moment of the 7/2+ ground state has been measured to be μ(7/2+135I) = 2.940(2)μN, thereby extending the known data on these states in odd-A I isotopes up to the neutron shell closure at N = 82. Shell-model calculations have been performed for the magnetic moments of 7/2+ states in the N = 82 isotones using free-nucleon and effective g-factors. The effective g-factors are obtained from a perturbation calculation that includes corrections for core polarisation and meson-exchange currents. The proton number dependence of the magnetic moments in the sequence of N = 82 isotones 133Sb-139La is discussed in terms of blocking of the Og9/2 to Og7/2 core polarisation with increasing Og7/2 occupancy. Systematics of all measured 7/2+ odd-proton moments for 74 ≤ N ≤ 82 are reviewed. © 1998 Elsevier Science B.V.
