Slow atoms in Rydberg states can exhibit specular reflection from a cylindrical surface upon which an azimuthally periodic potential is imposed. We have constructed a concave mirror of this type, in the shape of a truncated oblate ellipsoid of revolu

A lifetime spectrometer for use with an isotope-based DC positron beam is described. The system utilizes secondary electrons emitted from the sample and annihilation gamma rays to determine positron lifetimes. The device has been tested with porous s

Metalorganic vapor-phase epitaxially grown GaN films have been studied using beam positron annihilation spectroscopy. Positron lifetime and Doppler broadening of annihilation radiation measurements indicate that defects, probably Ga vacancies, are re

An ideal porous methyl-silsesquioxane (MSQ) film for low-k dielectrics would consist of a network of small, closed pores with homogeneous size distribution. In this work, we studied the pore size and interconnectivity between pores for porous MSQ fil
