Contribution

It introduces a hybrid multideterminant method combined with Lee-Suzuki renormalization for nuclear structure calculations of carbon isotopes.

Findings

Accurately reproduces experimental energy levels and binding energies.

Demonstrates the effectiveness of the hybrid multideterminant approach.

Shows applicability of chiral N3LO interactions in nuclear structure calculations.

Abstract

We perform calculations for the binding energies and low-lying levels of ${}^{10,11,12,13,14,15,16,17,18,19,20,21,22}C$ nuclei starting from the chiral $N3LO$ nucleon-nucleon potential within the framework of the Hybrid Multideterminant scheme. The calculations are restricted to 4 major harmonic oscillator shells, via the Lee-Suzuki renormalization scheme. The results are compared with the experimental data.
