Abstract: Abstract The activation technique allows much more precise measurements of neutron intensity, relative or absolute. This technique requires the knowledge of the Doppler Broadening Function to determine the resonance self-shielding factors in the epithermal range.… read more here.

Abstract: Doppler broadening in thermal ensembles degrades the absorption cross-section and the coherence time of collective excitations. In two photon transitions, it is common to assume that this problem becomes worse with larger wavelength mismatch. Here… read more here.

DOI: 10.3788/col201917.060201
Abstract: Atomic Doppler broadening thermometry (DBT) is potentially an accurate and practical approach for thermodynamic temperature measurement. However, previous reported atomic DBT had a long acquisition time and had only been proved at the triple point… read more here.
