【摘要】 本文用活化法分别以⁵⁶Fe（n,P）⁵⁶Mn和⁶³Cu（n,2n）⁶²Cu反应截面为标准,测量了14.61Mev中子的⁶⁴Zn（n,2n）⁶³Zn反应截面,其值分别为190.1±5.3mb和196.3±7.7mb。又以²⁷Al（n,P）²⁷Mg反应截面为标准,测量了14.13Mev、14.61Mcv和14.85Mev三个能点的⁶⁴Zn（n,2n）⁶³Zn反应截面,其值分别为116.0±8.7mb、189.4±14.2mb和197.2±14.8mb。活化生成核发射的γ射线用高纯锗（HPGe）γ谱议进行测量。更多还原

【Abstract】 The cross section for the ⁶⁴Zn（n,2n）⁶³Zn reaction was measured at 14.61Mev using the activation technique relative to well-known cross sections for the reference reactions ⁵⁶Fe（n,P）⁵⁶Mn and ⁶³Cu（n,2n）⁶²Cu with cross sections found to be 190.1+5.3 mb and 196.3+7.7 mb respectively. The Same measurements were also made at 14.13 Mev, 14.61 Mev and 14.85 Mev, where the cross sections of ²⁷Al（n,P）²⁷Mg rewere used for reference, and the the corresponding results 116.0+8.7 mb, 189.4+14.2 mb and 197.2+14.8 mb were thus given.The activated samples were counted for the r-activity using a HPGc detector.更多还原
