Relativistic invariance is incorporated within the framework of Poincar{é} invariant quantum mechanics. Based on a Malfliet-Tjon type interaction, observables for elastic and breakup scattering are calculated and compared to the nonrelativistic ones.3 pages, 3 figures, Contribution to the International Nuclear Physics Confernce, INPC 2007, Tokyo, Japan, June 3-8, 2007Nuclear Theorytext
