Summary
This study calculates properties of Carbon-12 using the ab initio no-core nuclear shell model. Results align with experimental data, highlighting the accuracy of the realistic nucleon-nucleon interaction.
Area of Science:
- Nuclear physics
- Computational physics
Background:
- The nuclear shell model is a fundamental framework for understanding atomic nuclei.
- Ab initio methods aim to solve nuclear many-body problems from first principles.
Purpose of the Study:
- To calculate nuclear properties of Carbon-12 using the ab initio no-core nuclear shell model.
- To investigate the influence of realistic nucleon-nucleon potentials on nuclear structure.
Main Methods:
- Utilized the ab initio no-core nuclear shell model.
- Derived effective Hamiltonians from CD Bonn and Argonne V8' nucleon-nucleon potentials.
- Employed finite harmonic oscillator basis spaces.
Main Results:
- Calculated binding energies, excitation spectra, and electromagnetic properties for Carbon-12.
- Extended calculations to larger model spaces.
- Achieved favorable agreement with experimental data.
Conclusions:
- The ab initio no-core nuclear shell model, with realistic nucleon-nucleon interactions, accurately predicts nuclear properties.
- The results underscore the importance of the underlying nuclear interaction over phenomenological fitting.
