Nuclear applications of inverse scattering, present ... and future?
R. S. Mackintosh
There now exists a practical method (IP) for the routine inversion of -matrix elements to produce the corresponding potential. It can be applied to spin-1/2 and spin-1 projectil…
Averaged coordination numbers of planar aperiodic tilings
Michael Baake, Uwe Grimm
We consider averaged shelling and coordination numbers of aperiodic tilings. Shelling numbers count the vertices on radial shells around a vertex. Coordination numbers, in turn, co…
Interplay between magnetic and spatial order in quasicrystals
E. Y. Vedmedenko, U. Grimm, R. Wiesendanger
The stable magnetisation configurations of antiferromagnets on quasiperiodic tilings are investigated theoretically. The exchange coupling is assumed to decrease exponentially with…
Radiative Habitable Zones in Martian Polar Environments
C. Cordoba-Jabonero, M. -P. Zorzano, F. Selsis +2
The biologically damaging solar ultraviolet (UV) radiation (quantified by the DNA-weighted dose) reaches the Martian surface in extremely high levels. Searching for potentially hab…
The mass of the neutron star in SMC X-1
A. K. F. Val Baker, A. J. Norton, H. Quaintrell
We present new optical spectroscopy of the eclipsing binary pulsar Sk 160/SMC X-1. From the He I absorption lines, taking heating corrections into account, we determine the radial…
Nucleosynthetic signatures of the first stars
Anna Frebel, Wako Aoki, Norbert Christlieb +16
The chemically most primitive stars provide constraints on the nature of the first stellar objects that formed in the Universe; elements other than hydrogen, helium and traces of l…
