High-Resolution Transmission Measurements of 233~U Using a Cooled Sample at the Temperature T=11 K

摘要

For the first time, high - resolution transmission data of 233~U have been obtained using a cooled sample. The samples were cooled to T=11K using a cryogenic device, which reduced the Dopple broadening of resonances by 50/100 compared to room-temperature measurements. The measurements were carried out at the Oak Ridge Electron Linear Accelerator over the energy range from 0.6 eV to 300 keV at the 80-m flight path station. Corrections were made for experimental effects, and the average total coross section in this energy range was determined. Results are compared to previous measurements.
