From the comparison of calculation based on theoretical formula of Blair and Anholt with the experimental result. The imaginary part of the atomic monopole amplitude Imb_0 was deduced and the R_0=Imb_0/Reb_0 was obtained as +1.8.

• 利用Blair-Anholt理论计算和实验结果的比较；引出了重要的原子碰撞单极报幅的虚部值参数Imb_0；并确认R_0=Imb_0/Reb_0的值为+1.；8。
