  1. The simulation can be divided into three processes sequentially : calculating the induced fission neutron rate of uranium and space distribution by mam - li neutron source, computing the total uranium fission neutron count rate and time distributions of 42 3he tubes, and calculating the neutron coincidence counting rate

    第一步,以ain ? li源為中子源,計算鈾的誘發裂變中子產生二率及空間分佈;第二步,以鈾的誘發裂變中子為中子源,計算化根』 ne管的總中子計數率及時間分佈;第三步,計算中子符合計數率。
  2. With the outer neutron source which can only induce 235u fission, it could possibly prove the presence of heu in a warhead by counting the coincidence neutrons. this method possibly provides one of necessary attributions in identifying the real nuclear warheads

    本文研究了用中子符合探測方式測量能量低於1mev的外中子源在核彈頭中誘發的裂變數,以判別模型中是否含有高濃鈾,從而作為判斷核彈頭的真偽的可行性。
