“…The number of fissions determined from the analysis of the fission chamber events permits to extract the yields of the three isomers of interest 134m,135m Te and 136m Xe. The isomer yields and ratios are compared to those of the references [8], [9] and [10] and are presented in Table 3 (8) and Table 4. One can notice the good agreement between the different measurements.…”

Abstract. In the framework of the C-BORD project of the H2020 programme to provide a safety chain for container inspection at border control points, CEA-DAM is involved to develop an identification method of Special Nuclear Material. Using active interrogation the main purpose is to specifically discriminate fissile actinides from fertile ones through the detection of γ-rays emitted by very short-lived isomers. We present here the interdependance of such a project with nuclear data. We first introduce the SNM identification method. Then, will be detailed the needs in nuclear data and first yields of specific short-lived isomers of 252 Cf spontaneous fission. Perspectives and conclusions will end the article.

“…Previous work (20,21) on isomeric gamma rays has been greatly expanded by the inclusion of very low-energy gamma rays and K x rays. The lov;-energy results have been used to further clarify the nature of previously reported (20,21) isomerism through unique assignment of the isomeric gamma rays to specific nuclei or the determination of K conversion coefficients.…”

“…A Ge(Li) photon detector viewed the face of one fragment detector in a manner closely resembling that used by John et a^. (20) and measured the energies (in the 30-1500 keV range) and emission times (up to 3 usee) of the delayed gamma rays. A Si(Li) photon detector viewed both fragment detectors and measured the energies (in the 6-100 keV range) and emission times (up to 3 lisec) of the delayed fragment K x rays and low-energy gamma rays.…”
