Summary
We calculated oxygen-16 nuclear structure, including charge form factor and longitudinal structure function, using advanced computational methods. Our findings align with experimental data, enhancing understanding of nuclear physics.
Area of Science:
- Nuclear Physics
- Quantum Chemistry
Background:
- Understanding nuclear structure is crucial for nuclear physics.
- Oxygen-16 is a key nucleus for nuclear structure studies.
Purpose of the Study:
- Calculate the charge form factor and longitudinal structure function for oxygen-16.
- Compare theoretical calculations with experimental data.
- Investigate the impact of ground-state correlations and interactions on nuclear observables.
Main Methods:
- Coupled-cluster [exp(S)] method for ground-state correlations.
- Realistic v18 nucleon-nucleon interaction.
- Urbana IX three-nucleon interaction.
- Center-of-mass corrections using a many-body expansion.
Main Results:
- Theoretical calculations for oxygen-16's charge form factor and longitudinal structure function were performed.
- Results were compared with available experimental data up to a momentum transfer of 4 fm(-1).
- The study demonstrates good agreement between theoretical predictions and experimental observations.
Conclusions:
- The coupled-cluster method with realistic interactions provides an accurate description of oxygen-16 nuclear structure.
- Ground-state correlations and three-nucleon interactions play a significant role in nuclear observables.
- The inclusion of center-of-mass corrections is essential for precise calculations.
