### Abstract

We present the finite size scaling method for studying the critical behavior of a quantum Hamiltonian ℋ (λ _{1}, ... , λ _{k}) as a function of a set of parameters {λ _{i}}. In this context, critical means the values of {λ _{i}} for which a bound state energy is non-analytic. In this case, the finite size corresponds to the number of elements in a complete basis set used to expand the exact Wave function of a given Hamiltonian.
