CXXIX. The alignment of Cobalt 58

Abstract

Abstract The technique for obtaining aligned Cobalt nuclei has been applied to the isotope Cobalt 58. An examination of the angular distribution of the 0·805 Mev γ-ray shows that this transition cannot be dipole but is probably quadrupole. The temperature dependence of this angular distribution gives for the nuclear magnetic moment a value of 3·5±0·3 nuclear magnetons. This result is discussed in relation to the nuclear shell-model.
