Precise magnetic moment of short-lived beta emitter 35Ar

The magnetic moment of the short-lived β emitter 35Ar ( I π =3/2 + , T 1/2 =1.77 s) has been remeasured by means of the combined technique of polarized nuclear beams and β-NMR. The obtained magnetic moment is 0.6322(2) μN. This value is consistent with the old data, but is one order of more magnitude precise. The value is well reproduced by the shell model calculation.
