Cross-over to classical behaviour for an Ising model with vacancies

A real space renormalization is applied to the Ising model for d ⩾ 3, allowing for the generation of vacancies. A fixed point structure is obtained that reflects the cross-over to classical behaviour as known from ϵ-expansion. The exponents found are an improvement over those obtained by the same method applied to the Ising model without vacancies.
