Sumario:The structural and energetical modifications undergone by a boson condensate in the presence of a static doping agent that provides an extra external field, and also the dynamics of the impurity subjected to the average force exerted by the atomic cloud were explored. A small 3He cluster was considered as an input. It was found that the effects of the doping agent upon cloud are essentially negligible.
