摘　　要：在球形相对论平均场模型下,采用NL1相互作用参数,对F同位素的基态和激发态进行计算,发现质子和最后一个质子在基态和激发态的均方根半径都是先减小后增加,而中子的均方根半径是一直增加的,而且随着中子数的增加,质子晕和皮现象消失.Under the model of the relativistic mean field theory, using NL1 interaction parameters to calculate F isotones of the ground states and the excited states, it could be found that the RMS radius of proton, the last proton in the ground state and excited state were reduced after the increase, and the RMS radius of the neutron had been increasing, but with the increase in the number of neutrons, proton and skin halo phenomenon would disappear.

关 键 词：相对论平均场 均方根半径 晕
