摘要: <正> 随着可控聚变反应研究的进展,近年来提出了D-T中子对将来可控聚变反应器材料损伤效应研究的重要性。这种损伤效应包括活化掺杂、溅射、反应等使材料的成分和结构发生变化的效应。它会改变材料性能、诱发化学腐蚀。原子核在(n,X)型反应中.除裂变外,Abstract: In this work, the forward and backward average projectional recoil ranges (R) of the residual 64Cu and 24Na with respect to neutron beam direction respectively in the 65Cu (n, 2n) 64Cu and 27Al (n, α) 24Na reactions induced by D-T neutrons were determined by thick-target-thick-catcher method. The results are RF = 73.8±13.1μg/cm2, RB = 10.0±5.1 μg/cm2 for 64Cu in Cu-target and RF = 282.9±11.0 μg/cm2, RB=20.0±3.4 μg/cm2 for 24Na in Al-target.
