We describe a novel approach to directly measure the energy of the narrow, low-lying isomeric state in 229Th. Since nuclear transitions are far less sensitive to environmental conditions than atomic transitions, we argue that the 229Th optical nuclea

Particles formed during the reaction of cerium with hydrogen fractured into stacked plates with fully separated plate thicknesses averaging 100 nm and a finer partially separated thickness of 30 nm. The phonon density of states of these particles, me

Inelastic neutron scattering experiments show that spin dynamics in the charge-ordered insulating ground state of the double layer perovskite YBaFe(2)O(5) is well described in terms of e(g) superexchange interactions. Above the Verwey transition at T

If a transition from an excited state to a lower state is in resonance with an absorption from the ground state of a nearby ion, efficient excited state relaxation may occur by cross relaxation. This is shown for the one-dimensional compound Pr(CH3C0
