dc.descriptionThe energy spectra of mesoscopic, i.e. few-body quantum systems are of great interest in several areas of physics such as nuclear physics, cluster physics or magnetism. One way to obtain an approximate spectrum is to diagonalize with reduced but carefully chosen basis sets. In this Letter we propose for the case of mesoscopic antiferromagnets to use the eigenstates of the rotational band Hamiltonian for this purpose. These states are not only well adapted, they can also be easily constructed.
