The key gamma energy for an isotope has an asterisk Eu-152 1408.0*(21) 122.1*(86) Co-57 271.8 d 136.5 14.4 The half-life of the J π =8 - isomer 152 Eu m 2 was obtained by measuring the decrease in intensity of the 90 keV γ ray from the cascade to the ground state. The half-life of this state was measured to be 95.8(4) min which is in agreement with and significantly more precise than the previously measured value of 96(1) min. 위키백과, 우리 모두의 백과사전.
