SUMMARY:Experiments on the Newly Functioning Spallation Neutron Source
  at Oak Ridge National Lab\, Physics Department Colloquium\, Haskell T
 aub\, University of Missouri-Columbia
DESCRIPTION:Abstract: We will discuss the present status of instrument
 ation for performing neutron scattering experiments on condensed matte
 r at the Spallation Neutron Source (SNS) at Oak Ridge National Laborat
 ory. The talk will focus on the high-energy-resolution quasielastic ne
 utron scattering spectrometer BASIS\, which can be used for investigat
 ing molecular diffusion in both solids and liquids and is one of three
  instruments currently available in the external user program. With th
 e SNS operating at about 40% of full power on target\, we discuss how 
 BASIS in its present configuration complements existing capabilities f
 or quasielastic neutron scattering at steady-state reactors. As an exa
 mple\, we show how measurements on BASIS help to provide a new "spin" 
 on a problem in the dynamics of molecular crystals that dates back to 
 the 1930s: the nature of solid-solid phase transitions to "rotator" ph
 ases that precede the melting of alkane crystals.
