The polyethylene (PE) with M, = 2.1 kg/mol and PDI 1.15 was obtained from the Pressure Chemical Co. PE solutions with volume fractions of 4>o = 0.10, 0.13 and 0.24 (in coil solutions) in deuterated o-xylene (>99 at% deuterium, C/D/N Isotopes Inc.) were measured using the NG3 30m SANS instrument at the NIST Center for Neutron Research of the National Institute of Standards and Technology. Incident neutrons of wavelength A = 6 A and two sample-to-detector distances of 1.33 and 6.5 m yielded a range of scattering wavevectors, 0.006 < Q < 0.4 A. In the cooling study, the...

Neutron Spin Echo Spectroscopy at the NIST Center for Neutron Research... 

Three high-resolution inelastic instruments are nearing completion at the NIST Center for Neutron Research (NCNR) (1) a disk chopper time-of-fiight spectrometer (2), a backscattering spectrometer (3), and a neutron spin echo (NSE) spectrometer. All three instruments will be available to researchers through reviewed proposals (4). Both the NSE and Backscattering spectrometers will be operation in early 1999 and the Disk Chopper Spectrometer shortly thereafter.
