FACILITY (REAC,2FR ILL) High flux reactor of Institute 2162200100015
Laue-Langevin. Also a perfect crystal neutron 2162200100016
interferometer is used. 2162200100017
INC-SOURCE (REAC) High flux reactor (neutron guide). 2162200100018
INC-SPECT Wave-length distribution has mean value 1.898+-0.003 2162200100019
Angstrom and width of about 0.7% and slightly 2162200100020
asymmetric form; measured in nondispersive position 2162200100021
without additional Ge-monochromator. 2162200100022
SAMPLE Gas vessel of Al alloy (Perradur S), with a 2162200100023
limit of ductility of 56 kp/mm/mm and a volume 2162200100024
of 11 cm**3 used at a pressure of 40 bars. The 2162200100025
quantity of gas used ranges between 0.5 and 1.0 2162200100026
grams. 2162200100027

Kr - 3.842, Xe - 6.168 . 2162200100035
METHOD (DIFFR) Two coherent beams traverse two different 2162200100036
path lengths in a gaseous sample of the material 2162200100037
to be studied. This causes a phase shift between 2162200100038
the two beams. By forcing these two beams to 2162200100039
interfere this phase shift can be determined from 2162200100040
the beam intensity oscillations as a function of 2162200100041
the density (i.e. the pressure, provided the 2162200100042
temperature is monitored) of the sample. For 2162200100043
more details and for formulas see Z.Physik,271,177. 2162200100044
DETECTOR (BF3) Two BF3 detectors. 2162200100045
CORRECTION For phase shift caused by the AL windows 2162200100046
of the pressure vessel. 2162200100047
Correction due to expansion of pressure vessels 0.5% 2162200100048
for H2, 1.7% for Ar. 2162200100049
Attenuation correction was considered for all gases, 2162200100050
but had noticeable influence for He-3 only. 2162200100051
ERR-ANALYS (ERR-S) Statistical errors. Gaussian error laws are 2162200100052
used for the calculation of the variances of the 2162200100053
data. 2162200100054
