Optical and Structural Characterization
Research gap analysis derived from 2 physics papers in our local library.
The gap
The optimal model selection for true coincidence summing correction in gamma spectrometric measurements requires further investigation.
Consensus across the literature
Most papers leave open the specific conditions under which their methods are most effective, particularly regarding noise level, baseline drift magnitude, thickness uncertainty, and dataset types.
