Abstract: The lack of good quality data for Cd may be a source for the long standing discrepancy between resonance integral measurements and the values calculated from the resolved resonance parameters. Therefore it was suggested that some new measurements should be carried out at IRMM Geel on natural Cd to try to resolve this problem. These measurements were performed in collaboration with the IAEA, Vienna in the framework of NUDAME. Measurements with thick natural Cd sample enriched to 99.99% in Cd were performed. The sample had a thickness of 25.8 mm corresponding to 0.120 at/b. The experiment was built up at flight path number 2 of GELINA. The neutron detector, a Li-glass scintillator, was placed at 26.45 m from the neutron producing target. The Li-glass had an effective diameter of 110 mm and was 12.7 mm thick. The data obtained in our measurements was compared with the existing one in ENDF/B-VI library. In this paper we report our very first results from the analysis of the data obtained in these measurements. The resonance parameters were extracted from the transmission data by using the analysis code REFIT.
