Abstract
The total neutron cross section of 147Pm has been measured from 0.01 to 1000 eV, using compacted oxide samples in the Materials Testing Reactor (MTR) fast chopper. After correcting the data for decay product 147Sm content and water contaminant bias, the total cross section of 147Pm at 0.0253 eV was found to be b. Resonance parameters were determined up to 250 eV by shape-fitting and area analysis, and a negative energy resonance has been postulated to fit the data at thermal. From these parameters a resonance absorption integral of 2192 ± 100 b and a neutron s-wave strength function have been obtained.
