Doubly-magic nature of 56<\/sup>Ni: Measurement of the ground state nuclear magnetic dipole moment of 55<\/sup>Ni<\/em><\/p>\n

The nuclear magnetic moment of the ground state of 55<\/sup>Ni (Iπ<\/sup>=3\/2–<\/sup>, T1\/2<\/sub>=204 ms) has been deduced to be |&mul(55<\/sup>Ni)|=(0.976&plusminus;0.026)\u2002μN<\/sub> using the β-ray detecting nuclear magnetic resonance technique. Results of a shell model calculation in the full fp<\/em> shell model space with the GXPF1 interaction reproduce the experimental value. Together with the known magnetic moment of the mirror partner 55<\/sup>Co, the isoscalar spin expectation value was extracted as <Σσz<\/sub>>=0.91&plusminus;0.07. The <Σσz<\/sub>> shows a trend similar to that established in the sd<\/em> shell. The present theoretical interpretations of both &mul(55<\/sup>Ni) and <Σσz<\/sub>> for the T=1\/2, A=55 mirror partners support the softness of the 56<\/sup>Ni core.<\/p>\n","protected":false},"excerpt":{"rendered":"
