Abstract: As part of nuclear data library, neutron resonance parameter (NRP) plays a very important part in the application for national defense, industrial production and theoretical research. For some reason, there are no such research conditions for NRP in China, either experimental or theoretical. The analysis of NRP should base on experimental data, so a total cross-section measurement was done on the Pohang Neutron Facility (PNF), yielding a new set of transmission data of ¹⁶⁹Tm below 100 eV, as well as a new set of NRP of ¹⁶⁹T using SAMMY code. Taking all data collected for ¹⁶⁹Tm NRP into consideration, a new set of ¹⁶⁹Tm NPR was evaluated and recommended. After this work, the methodology and analyzing-flow for NRP evaluation were summarized, as a technological reservation for the future work.
