TITLE Differential cross section for n-p elastic scattering 1089200100011
in the angular range 51 deg. to 180 deg. at 647.5 MeV.1089200100012
FACILITY (MESON,1USALAS) Los Alamos meson physics facility 1089200100013
INC-SOURCE (P-D) Protons on deuterium with steel collimator 1089200100014
SAMPLE Liquid hydrogen with refrigeration system. Surrounded 1089200100015
with 0.013-mm aluminized mylar, vacuum space, and 1089200100016
mylar jacket. 1089200100017
DETECTOR (TELES,SCIN,SCIN) Differential range telescope with 4 1089200100018
scintillation counters and copper absorbers used to 1089200100019
detect scattered protons. Neutron flux monitored with 1089200100020
two telescopes looking at a polyethylene scatterer, 1089200100021
each using two scintillation counters separated by 1089200100022
copper absorbers. 1089200100023
(MAGSP) Magnetic spectrometer system using four multi- 1089200100024
wire proportional counters and three scintillation 1089200100025
detectors used to detect scattered protons 1089200100026
MONITOR Absolute normalization uses known cross sections for 1089200100027
neutron-proton collisions yielding deuterium and 1089200100028
neutral pions. 1089200100029
METHOD (TOF) Magnetic spectrometer used to obtain time of 1089200100030
flight information for scattered protons. Background 1089200100031
measured using empty target. Computer program KIOWA 1089200100032
used to derive cross sections from raw data. Since 1089200100033
monitor only good for angles less than 13.2-degrees, 1089200100034
average value of absolute normalization to dual-flux- 1089200100035
monitor-counts ratio used for relative normalization 1089200100036
of larger angles. 1089200100037
CORRECTION Cross sections generated by computer program KIOWA 1089200100038
corrected for proton and deuteron absorption in 1089200100039
spectrometer system. 1089200100040
ERR-ANALYS Errors in angles due to systematic errors in 1089200100041
-spectrometer alignment 1089200100042
-multiple scattering and geometric resolution effects 1089200100043
in spectrometer 1089200100044
-multiple scattering of protons in target and 1089200100045
scintillators 1089200100046
(ERR-S) Only statistical errors are quoted, 1089200100047
does not include 1089200100048
(ERR-1) normalization uncertainty of 7%. 1089200100049
