Electric dipole-dipole interaction in CaF2 : R3+ and SrF2 : R3+ : Results of ITC and EPR experiments
The present study deals with total R ~ + concentrations ranging from about 0.02 to 6 Mol. % ! The different types of local charge compensation centers have been investigated by means of EPR, electric field effect in EPR and ITC and it was found that : i) dipole-dipole interactions significantly modify the shape of the ITC-curves even at moderate R3+
متن کاملNeutron Electric Dipole Moment Experiments
The possibility of a non-zero value for neutron EDM continues to be of central importance in physics and cosmology. A non-zero neutron EDM would be a direct evidence for time-reversal symmetry violation. It also implies CP-violation under the assumption of CPT invariance. To date, only two examples of CP-violation have been found: decays of neutral K mesons and B mesons. CP-violation is believe...
متن کاملElectric dipole polarizabilities and C6 dipole-dipole dispersion coefficients for sodium clusters and C60.
The frequency-dependent polarizabilities of closed-shell sodium clusters containing up to 20 atoms have been calculated using the linear complex polarization propagator approach in conjunction with Hartree-Fock and Kohn-Sham density functional theories. In combination with polarizabilities for C(60) from a previous work [J. Chem. Phys. 123, 124312 (2005)], the C(6) dipole-dipole dispersion coef...
متن کاملElectric dipole polarizabilities and C6 dipole-dipole dispersion coefficients for alkali metal clusters and C60
The frequency dependent polarizabilities of closed-shell alkali metal clusters containing up to ten lithium, potassium, and rubidium atoms have been calculated using the linear complex polarization propagator approach in conjunction with Hartree–Fock and Kohn–Sham density functional theory. In combination with polarizabilities for C60 from a previous work [J. Chem. Phys. 123, 124312 (2005)], th...
متن کاملLithium electric dipole polarizability
The electric dipole polarizability of the lithium atom in the ground state is calculated including relativistic and quantum electrodynamics corrections. The obtained result αE = 164.074 0(5) a.u. is in a good agreement with the less accurate experimental value of 164.19(1.08) a.u. The small uncertainty of about 2ppm comes from the approximate treatment of quantum electrodynamics corrections. Ou...
