摘　　要：发展了包括奇时间(time-odd)分量的三轴形变的RMF理论模型,采用包含σ和ω介子自相互作用以及微观质心修正的PK1有效相互作用,自洽考虑了由于奇A核中的耒配对的核子对时间反演不交性的破坏所导致的重子流,以41Ca为例,研究了奇时间分量对重子流以及原子核性质的影响．The triaxial deformed Relativistic Mean Field （RMF） model including the time-odd component is developed. The magnetic potential and baryon current in ^41Ca and their influence on the magnetic moment, single particle level splitting for time reversal states and other properties are investigated in triaxial deformed RMF model with the spatialcomponent of vector meson fields by using PK1 effective interaction, which includes the self-coupling of σ and ω meson fields as well as the microscopic correction for the center of mass.
