Abstract

A close to converged binding energy of the e+Li ground state was computed using the stochastic variational method (SVM). A basis containing 1200 explicitly correlated Gaussians (ECG) were used for the final calculation. The binding energy of e+Li6 was 0.0024785 hartree and the binding energy of e+Li7 was 0.0024791 hartree. The derived core annihilation rate was 1.66�06 s-1, about 6% larger than the fixed core stochastic variational method.
