Variational free complement method with Gaussian-expanded complement functions: convergence with fixed Gaussian expansion length

Abstract

For the free complement theory with Gaussian-expanded complement functions, the energy convergence of $n_{\mathrm{G}}=\mathrm{constant}<\infty ,n\to \infty$ is discussed, where $n_{\mathrm{G}}$ is the number of the Gaussian functions in the STO-$n$G expansion.
