Observation of anisotropic diffusion of light in compacted granular porous materials
Erik Alerstam, Tomas Svensson
It is known that compaction of granular matter can lead to anisotropic mechanical properties. Recent work has confirmed the link to pore space anisotropy, but the relation between…
Photon and Eta Production in p+Pb and p+C Collisions at sqrt{sNN} = 17.4 GeV
WA98 Collaboration
Measurements of direct photon production in p+Pb and p+C collisions at are presented. Upper limits on the direct photon yield as a functio…
Event-by-event charged-neutral fluctuations in Pb+Pb collisions at 158 A~GeV
WA98 Collaboration
Charged particles and photons have been measured in central Pb+Pb collisions at 158 A GeV in a common ( - )-phase space region in the WA98 experiment at the CERN SPS. The mea…
Disordered, strongly scattering porous materials as miniature multipass gas cells
Tomas Svensson, Erik Adolfsson, Märta Lewander +2
Spectroscopic gas sensing is both a commercial success and a rapidly advancing scientific field. Throughout the years, massive efforts have been directed towards improving detectio…
Laser spectroscopy of gas confined in nanoporous materials
Tomas Svensson, Zhijian Shen
We show that high-resolution laser spectroscopy can probe surface interactions of gas confined in nano-cavities of porous materials. We report on strong line broadening and unfamil…
Azimuthal Anisotropy of Photon and Charged Particle Emission in Pb+Pb Collisions at 158 A GeV/c
WA98 Collaboration, M. M. Aggarwal
The azimuthal distributions of photons and charged particles with respect to the event plane are investigated as a function of centrality in Pb + Pb collisions at 158 A GeV/c in th…
