Focus Areas

• Nuclear Level Scheme: Mapping nuclear energy levels to understand their structure and transitions.

• Nuclear Level Density (NLD): Investigating the density of energy levels, crucial for statistical nuclear models and reaction rate calculations.

• Radiative Strength Function (RSF): Studying gamma-ray emission probabilities from excited nuclear states to refine models of decay and photonuclear reactions.

Methodology

• Theoretical Work: Developing and applying nuclear models to interpret experimental data and predict nuclear behavior, including statistical and mean-field approaches.

• Experimental Work: Using the gamma-gamma coincidence spectrometer at the Dalat Nuclear Research Institute to identify precise gamma transitions and construct nuclear level schemes.

Experimental Techniques

• Gamma-Gamma Coincidence Spectroscopy: Enhances resolution and accuracy by correlating cascaded gamma-ray pairs.

• Data Analysis: Involves spectrum unfolding, level density fitting, and extraction of RSFs and NLDs.

Applications & Impact

• Enhances understanding of nuclear structure in medium and heavy nuclei.

• Provides evaluated data for the ENSDF library.

• Supports nuclear reaction modeling in reactor physics and astrophysics.

• Contributes to the development of advanced nuclear models and simulation tools.
