【摘要】 为了探寻超密核存在的可能性,用铅玻璃契仑柯夫全吸收谱仪在²⁵²Cf自发裂变中搜索高能γ射线。给出能量在50到240兆电子伏区域的γ射线出现几率的上限值为1.4×10^-6/裂变（置信水平95％）.更多还原

【Abstract】 In order to investigate the poss ibility of the existence of the ultradense nuclei, wehave used a lead glass Cerenkov total absorption spectrometer to search for highenergy γ rays in the spontaneous fissions of ²⁵²Cf. It follows that the upper limit ofthe probability of γ rays in the energy range between 50 and 240 MeV is 1.4 ×10^-6/fission （95% confidence level）.更多还原
