Abstract

The nuclear moments of 13B(Iπ = 3/2-, T1/2 = 17.36ms) have been re-measured precisely in order to establish the spin manipulation technique for the study of the alignment correlation term in mass system A = 13. From the β-NMR on 13B in Pt, the magnetic moment was determined as μ(13B) = 3.1778(5)μN. From the β-NQR on 13B in TiO2, the Q moment has been determined as Q(13B) = 36.6(8)mb. We have measured the alignment correlation term α_E for 13B β decay for the first time and obtained a preliminary result as α(-(13B) = 0.15(12)%/MeV.
