摘　　要：本文介绍用厚 TiDx 靶测量 D(~4He,~4He)D 弹性反冲激发函数的方法.测量了2.7～4.5Mevθ=30°的激发函数.本文还将测量结果与卢瑟福反冲截面进行了比较,发现在该能区内.D(~4He,~4He)D 弹性反冲微分截面比卢瑟福反冲截面大很多.A measurement method of D(~4He,~4He)D elastic recoil excitationfunction using thick target is presented.The excitation function inenergy region 2.7～4.5MeV at θ=30°was measured.The measured valueswere compared with Rutherford recoil cross sections.It was found that inthis energy region,D(~4He,~4He)D recoil cross sections were much largerthan Rutherford recoil cross sections.
