Abstract
The magnetic moment of 28P (I π = 3 + , T1/2 = 270.3 ms) in the ground state has been measured by the \(\upbeta \)-nuclear magnetic resonance method for the first time. The measured magnetic moment of \(\vert \upmu (^{28}\)P)∣ = 0.309(9) \(\upmu _{{\rm N}}\) is well reproduced by the shell model value of +0.306 \(\upmu _{{\rm N} }\). The shell model calculation also yields a proton density distribution with a long tail. The present results provide a strong confirmation of the configuration of the 2s 1/2 proton which should lead to the proton halo.
