Twin photons, pairs of photons with entangled properties, are now easily produced from nonlinear optical crystals and experiments with these pairs are routinely done at different laboratories [1]. Is it possible to study the same kind of properties with twin atoms, i.e., pairs of massive particles also with entangled properties obtained simply by breaking diatomic homonuclear molecules? In this article we discuss experiments, calculations and proposal that point to this possibility.
