We use numerical integrations to study the asymptotical behaviour of ahomogeneous but anisotropic Bianchi type IX model in General Relativity with amassive scalar field. As it is well known, for a Brans-Dicke theory, theasymptotical behaviour of the metric functions is ruled only by the Brans-Dickecoupling constant with respect to the value -3/2. In this paper we examine ifsuch a condition still exists with a massive scalar field. We also show that,contrary to what occurs for a massless scalar field, the singularityoscillatory approach may exist in presence of a massive scalar field having apositive energy density.Comment: 31 pages, 7 figures (low resolution
