| Abstract: | Magnetic moments around the Z=40 shell closure have been established using nuclear magnetic resonance on oriented nuclei (NMR/ON)
in iron. From the resonance frequencies we established |μ(91Y;9/2+)|=5.96(6)μN, |μ(95Zr;5/2+)|= 1.103(23)μN, | μ(97Nb;9/2+)| = 6.153(5)μN. From the electric quadrupole alignement of95Zr+95Nb in a Zr single crystal Q(95Zr)=+0.29(5)b and Q(95Nb)<0 have been derived. The results obtained are discussed using the Nilsson deformed single particle model. It is shown
that for certain deformation regions, a measurement of the magnetic moment can give information on the nuclear quadrupole
deformation.
