“…The data source of β 2 , E i , and the nucleonic configurations is literature [26], and the source of E γ and I γ data is the National Nuclear Data Center [30]. age of the above values, weighted as the square-reciprocal of their corresponding uncertainties [27,28]. The final isomeric ratio obtained in this manner was 0.29 ± 0.11, which is consistent with the results in literature within the uncertainty (which are also presented in Table 3) [6,7].…”

The isomeric ratio of 184m, gRe and the half-life of 184gRe were measured in the 185Re (n, 2n) 184Re reaction at 14.8 MeV, as well as the uncertainty was discussed in detail. The measurements were performed by the activation method implemented for the rhenium sample using the K-400 neutron generator at the Chinese Academy of Engineering Physics (CAEP). Isomeric state and ground state nuclei of 184Re were identified by their γ-ray spectra. In order to eliminate the effect of the γ-ray emitted from the isomer on the counting of the ground state characteristic peak, the isomeric ratio of 184m, gRe was calculated to be 0.29 ± 0.11 according to the neutron activation cross-section formula. This result is consistent with previous data within the uncertainty, whereby it can be used to determine parameters that characterize the dependence of the level density on the excitation energy and angular momentum. Through exponential function fitting and a detailed discussion of the uncertainty evaluation, the new recommended half-life of 184gRe was determined as 35.43 ± 0.16 d, which was consistent with the currently recommended value, however, the uncertainty assessment of the latter was barely documented. In addition, this work indicates that the half-life of the ground state can be obtained by eliminating the contamination of the γ-rays emitted from the isomer, which provides the possibility to determine the half-lives of nuclides containing isomers.

ccurate and reliable nuclear decay database is essential for fundamental and applied nuclear relative researches. However, the decay data is not as accurate as usual impression and still need improvement. Hence, the new Chinese nuclear decay database in fission product mass region (A=66-172) has been developed under the joint efforts of CNDC working group, based on several major national evaluated data libraries. Totally 2358 nuclides have been included in this decay database. Two main data formats, ENSDF and ENDF, are adopted. For the total mean  and  energies, data from total absorption gamma ray spectroscopy measurement are adopted when available. For some nuclides without experimental measurements, theoretically calculated values were added.
