Some optical properties of graphite from IR to millimetric wavelengths
Robert J. Papoular, Renaud Papoular
Far infrared(FIR) data on the optical properties of graphite are presently lacking. An important step towards filling this gap was taken by Kuzmenko et al. (2008) who measured, on…
Effects of structural and chemical disorders on the visible/UV spectra of carbonaceous interstellar grains
R. J. Papoular, S. Yuan, R. Roldan +2
The recent spectacular progress in the experimental and theoretical understanding of graphene, the basic constituent of graphite, is applied here to compute, from first principles,…
An enduring puzzle: the width variations of the 2175 Angstrom extinction band
Robert J. Papoular, Renaud Papoular
Graphene, a single infinite, planar, sheet of graphite, has the same dielectric resonances as bulk graphite, but solid state theory indicates that its features are about half as wi…
A polycrystalline graphite model for the 2175 Angstrom interstellar extinction band
Robert J. Papoular, Renaud Papoular
A random, hydrogen-free, assembly of microscopic sp2 carbon chips, forming a macroscopically homogeneous and isotropic solid, is proposed as a model carrier for the UV interstellar…
Anomalous spin density distribution on oxygen and Ru in CaSrRuO: A polarised neutron diffraction study
A. Gukasov, M. Braden, R. J. Papoular +2
By means of polarized neutron diffraction in a magnetic field of 7.0 T at 1.6 K an anomalously large magnetization density is observed on the in-plane oxygen in CaSr$_{0.5}…
