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).
