Contribution

It introduces a novel combination of the Hybrid Multideterminant approach with the Lee-Suzuki renormalization for ${}^6Li$ binding energy calculation.

Findings

Binding energy of about 31 MeV for ${}^6Li$

Results are within a few hundred keV uncertainty

Center of mass diagnostics are discussed

Abstract

We perform an ab-initio calculation for the binding energy of ${}^6Li$ using the CD-Bonn 2000 NN potential renormalized with the Lee-Suzuki method. The many-body approach to the problem is the Hybrid Multideterminant method. The results indicate a binding energy of about $31 MeV$, within a few hundreds KeV uncertainty. The center of mass diagnostics are also discussed.
