The field of medical imaging with polarized rare gases, just five years old, has brought optical scientists together with medical researchers to perfect techniques and pursue new opportunities for biomedical research. This review, written for the likely reader of these volumes, aims to present the field from several perspectives. The historical perspective shows how applications of nuclear pola...

The effect of mass on gas/organic-surface energy transfer is explored via investigation of the scattering dynamics of rare gases (Ne, Ar, and Kr) from regular (CH3-terminated) and omega-fluorinated (CF3-terminated) alkanethiol self-assembled monolayers (SAMs) at 60 kJmol collision energy. Molecular-beam scattering experiments carried out in ultrahigh vacuum and molecular-dynamics simulations ba...

The influence of the surroundings on the linear dipole polarizability a and second hyperpolarizability 7 is discussed in terms of the density om of isotropically distributed matter as well as the density qp of thermal black-body radiation photons, a and 7 of the rare gas atoms are studied as examples. At standard conditions, both effects are of comparable size for the rare gases. Possible conse...
