在无规取向的超精细磁谱中,六个峰的相对强度比是3:2:1:1:2:3。但随着内磁场方向和γ射线传播方向间的夹角θ_m的不同,则相对谱线强度有所变化,这就是~(57)Fe核的塞曼谱中容许跃迁的角度依赖关系。 轴对称电场梯度(η=0)在~(57)Fe核处产生的四极双峰谱的相对强度与电场梯度主轴方向和γ射线间的夹角θ_q, In a randomly oriented superfine magnetic spectrum, the relative intensity ratio of the six peaks is 3: 2: 1: 1: 2: 3. However, with the difference of θ_m between the direction of the internal magnetic field and the direction of γ-ray propagation, the relative line intensity changes, which is the angular dependence of the allowable transition in the Zeeman spectrum of ~ (57) Fe nuclei. Axisymmetric electric field gradient (η = 0) in the ~ (57) Fe nucleus quadrupole peak generated by the relative intensity of the electric field gradient and the direction of the main axis and the angle between the γ-ray θ_q,
