Lattice Calculation of the Sn Isotopes near the Proton Dripline
Abstract
We present the first ab initio lattice calculations of the proton-rich tin isotopes ^{99}Sn to ^{102}Sn using nuclear lattice effective field theory with high-fidelity two- and three-nucleon forces. For a given set of three-nucleon couplings, we reproduce binding energies with ∼1% accuracy for the even-even systems and obtain energy splitting and two-nucleon separation energies in agreement with experiment. Our results confirm the N=50 shell closure and reveal that the binding energy of ^{99}Sn lies below values extrapolated from heavier isotopes.
