SUMMARY:Surprises! and Puzzles? from Probing Neutral Atoms Trapped in 
 Noble Gas Ice\, R. G. Herb Condensed Matter Seminar\, Jaideep Singh\, 
 Argonne National Lab
DESCRIPTION:Our goal is to demonstrate that a guest species trapped in
  a solid noble gas matrix is a quiet environment for the manipulation 
 of nuclear spins. Applications include studies of rare isotopes and te
 sts of fundamental symmetries. We have studied the optical spectrum of
  Ytterbium atoms embedded in a solid Neon matrix with the goal of spin
  polarizing the Yb-171 nuclei via optical pumping. The optical spectru
 m of the embedded atoms resembles that of free atoms with significantl
 y matrix-shifted line-centers.  We have observed spectral line-widths 
 that vary by at least two orders of magnitude depending on the exact n
 ature of the transition.  Although some of the transitions are nanomet
 ers wide\, we have evidence that they are homogenous\, making optical 
 pumping feasible. In this talk\, we'll present our most recent results
  and discuss our progress towards the optical pumping of Yb-171.
