Abstract

The Doppler broadening ofthe lower energy neutron absorption resonances ofnatural hafnium, tantalum, iridium and rhenium have been studied for the purpose of measuring temperature in remote or isolated environments. Three methods for the determination of sample temperature from neutron transmission data were studied and a critical comparison ofthe efficacy ofeach method made. Fitting the observed resonance line shapes with analytical expressions incorporating instrument resolution and resonance parameters provided the most accurate measure ofsample temperature with an estimated uncertainty of 10 C at 1000 C and did not require prior calibration experiments to be performed.
