Figure 10 The numerical results of pj for j1=j2=j3=j4=20 and various θ→≡(θ1,θ2,θ3,θ4), φ→≡(φ1,φ2,φ3,φ4), where the x axis shows the recoupling spin j and the y axis shows the numerical value of pj. These figures show that pj has a peak near j=j0≡|j1n^1+j2n^2|, and this peak shrinks with the angle arccos(n^1·n^2) decreasing. (a) θ→=(π2,π2,7π16,9π16), φ→=(0,π8,π16,π16). (b) θ→=(π2,π2,3π8,5π8), φ→=(0,π4,π8,π8). (c) θ→=(π2,π2,π6,5π6), φ→=(0,2π3,π3,π3). (d) θ→=(π2,π2,π16,15π16), φ→=(0,7π8,7π16,7π16).
