Progress Towards Operation of a Deuterium Cold Neutron Source at the NCNR

June 1, 2020
Author(s)
John M Jurns, Michael Middleton, Robert E. Williams
The NIST Center for Neutron Research (NCNR) operates a 20 MW research reactor that produces neutrons for a suite of 30 neutron scattering instruments. 70% of these instruments use cold neutrons (E 2), which is in turn cooled by a recently commissioned 7 kW

Fast Vibrational Relaxation of OH (v=9) By Ammonia and Ozone

June 1, 2001
Author(s)
S A. Nizkorodov, W W. Harper, David Nesbitt
Vibrational relaxation of OH(X 2II) in the Ņ=9 state by O 3 and NH 3 has been studied via flash-photolysis using high-resolution direct infrared absorption detection of OH in the Ņ= 11
