Abstract：
Nuclear structure of proton-rich unstable nucleus²⁸P has been studied by measuring its g-factor for the first time. The g-factor of²⁸P (I^π=3⁺, T_1/2=270.3 ms) was measured by means of β-NMR technique combined with the new polarization technique for charge exchange reaction product in the intermediate energy heavy ion collisions. The obtained g-factor of g=0.1028(27) is very much quenched from the Schmidt value, but is well reproduced by the shell model (+0.102). In connection with the magnetic moment of the mirror partner and the β-ray transition probability, the orbital angular momenta and intrinsic spins of protons and neutrons have been determined as 〈l_p〉=0.43(29), 〈l_n〉=1.85(29), 〈S_p)=0.28(4), and 〈S_n〉=0.44(4).
