摘要
描述了用实验方法测量快中子引起的背向溅射，测量了Mg、Al、Sc、V、Fe、CO、Cu、Zr、Au和316型不锈钢等10种材料的背向溅射产额，并与正向产额进行了比较，发现背向和正向溅射产额的比值与核反应的类型有关．本实验的结果同其它小组的结果进行了比较，并用溅射理论对实验结果进行了解释．
An experimental method of measuring backward sputtering induced by fast neutron is described. Backward sputtering yields of 10 malterials of Mg, Al, Sc, V, Fe,Co, Cu, Zr, An and type 316 stainless steel are measured and compared with forward sputtering yields. It is found that the ratios of backWard to forward sputtering yields depend on the kinds of reactions. The present results are compared with other experimental resultS and explained using sputtering theory.
