• 中文摘要： 本文研究反跳銅原子在Copper oxinate(包括含水及無水物)結晶系統中之化學效應。實驗結果顯示穩定結晶系(B-型)之初期存留較不穩定結晶系(a-型)為高，韭睢含水及無水物結晶時皆然。經中子照射之固體結晶受熱後，其重新結合成Parent species之敏感度，B-型結晶亦較a-型為高。以上所得之結果與另一結晶系統Copper phthalocyanine之結果頗為一致，本文試從結晶構造之觀點加以說明。結晶水在此系統中並未發覺有何可察覺程度之影響。前處理對反跳原子之化學效應亦作檢討，結果顯示中子照射前經加熱或r-線照射處理者，其初期存留均有顯著之變化。
• 英文摘要： The effect of crystalline polymorphism on the recoil atoms in copper oxinatesof dihydrate and anhydrite have been studied. It was found that the initial retentionin the stable forms(B)are higher than those in the metastable forms(a) for bothanhydrite and dihydrate. Upon heating the irradiated crystals, the sensitivity ofrecombining into parent species in the B-crystals is higher than that of a一crystalsboth in the case of anhydrite and dihydrate. All these relationships are consistentwith the results of copper phthalocyanines and are interpreted from the crystal-lographical point of view. The effect of water of crystallization on the behavior ofrecoil atom was not important in the present study. The effect of pretreatmentof copper oxinate before neutron irradiation was also studied. A reduced initialretention was obtained with the samples which have subjected to the preheatingand prior gama irradiation.
