Detection of magnetic circular dichroism using a transmission electron microscope
Article Abstract:
The direct experimental detection of magnetic circular dichroism in a transmission electron microscope (TEM) is reported. Measurements of electron energy-loss magnetic chiral dichroism (EMCD) are compared with X-ray magnetic circular dichroism (XMCD) spectra obtained from the same specimen that, together with theoretical calculations, show that chiral atomic transitions in a specimen are accessible with inelastic electron scattering under particular scattering conditions.

Soft equations of state for neutron-star matter ruled out by EXO 0748-676
Article Abstract:
A determination of the mass and radius of the neutron star EXO 0748-676 that appears to rule out all the soft equations of state of neutron-star matter is reported and if this object is typical, then condensates and unconfined quarks do not exist in the centers of neutron stars. Equations of state with condensate interiors reveal large-radius, low-mass neutron stars that are mostly excluded by the assumed measurements.
