The results of a large shell-model calculation of a pseudo-nucleus which displays striking behavior suggestive of rotational phenomena are presented. In these calculations, a specific and physically reasonable single-particle structure is given to the wave functions, and an explicit two-body residual interaction is used. The calculations show the coupling of key low-lying neutron and proton states of valence particles can lead to collective rotational features which appear to be more distinct and which extend to higher angular momenta as the number of particles increases and that those states which are rotational are dominated by states formed by coupling J = 0 and J = 2 two-particle states. Considerable supporting evidence is offered for the validity of the assumptions of the interacting boson model. 2 references. (JFP)
