Impurity scattering in a two-dimensional electron gas subject to a perpendicular magnetic field.
(1998)
We have calculated the Landau level (projected) Green's functions and the density of states of a two-dimensional electron gas in a perpendicular magnetic field as effected by impurity scattering using several different ...
Heavenly metal: A study of neutron-capture element abundances in metal-poor galactic halo stars.
(1998)
New abundances for neutron-capture elements in a large sample of metal-poor giants from the Bond survey in addition to 3 well known individual cases, are presented. The spectra for the Bond Giants were acquired with the ...
"'Tis something, nothing", a search for radio supernovae.
(1998)
We report VLA radio observations of 29 SNe with ages ranging from 10 days to about 90 years past explosion. Included are detections of known radio SNe 1950B, 1957D, 1970G, 1983N, the suspected radio SN 1923A, and the ...
