.BACKGROUND FROM STRUCTURAL MATERIAL WAS NEGLIGIBLE. 2201800100020
METHOD .DOPPLER-BROADENED GAMMA-ENERGY DISTRIBUTIONS WERE 2201800100021
MEASURED TO DETERMINE THE ANGULAR DISTRIBUTION OF 2201800100022
LI-7 RECOILS, AND THEREBY DETERMINE THE NEUTRON 2201800100023
ANGULAR DISTRIBUTION. 2201800100024
(TOF) TIME-OF-FLIGHT TECHNIQUE WAS USED TO SUPPRESS 2201800100025
BACKGROUND FROM NEUTRONS. 2201800100026
DETECTOR (HPGE) A 70 CM3 PURE GERMANIUM DETECTOR AT A DISTANCE 2201800100027
OF 1.2 M WAS USED FOR GAMMA DETECTION. THE DETECTOR 2201800100028
WAS WELL SHIELDED IN A COLLIMATOR, CONSISTING OF 2201800100029
PARAFFIN, LITHIUM CARBONATE AND LEAD. A BRASS SHADOW 2201800100030
BAR SHIELDED THE DETECTOR FROM DIRECT TARGET 2201800100031
NEUTRONS. 2201800100032

SAMPLE .METALLIC LITHIUM CYLINDER, 36.8 MM DIAMETER BY 2201800100034
29.9 MM HIGH, HOUSED IN AN ALUMINIUM CONTAINER 2201800100035
WITH 0.2 MM THICK WALLS. THE LITHIUM WAS ENRICHED 2201800100036
TO 99.98 PER CENT IN LI-7. THE SAMPLE WAS MOUNTED 2201800100037
10 CM FROM THE NEUTRON TARGET. 2201800100038
CORRECTION .SEVERAL CORRECTIONS WERE TAKEN INTO ACCOUNT, I.E. 2201800100039
A. THE ENERGY/ANGLE DISTRIBUTION OF THE PRIMARY 2201800100040
NEUTRONS, 2201800100041
B. THE SCATTERING IN THE SAMPLE, 2201800100042
C. THE COMBINED EFFECT OF HALF-LIFE AND STOPPING 2201800100043
POWER, 2201800100044
D. GAMMA DETECTOR RESOLUTION. 2201800100045
THESE CORRECTIONS WERE CALCULATED WITH MONTE-CARLO 2201800100046
TECHNIQUES. 2201800100047
ERR-ANALYS (DATA-ERR) NO DETAILS GIVEN. 2201800100048
ANALYSIS .IT WAS ASSUMED THAT THE C.M. ANGULAR DISTRIBUTIONS 2201800100049
COULD BE EXPRESSED AS A SUM OF LEGENDRE PLYNOMIALS. 2201800100050
LEAST-SQUARES FITTING TO THE EXPERIMENTAL DATA THEN 2201800100051
DIRECTLY GAVE THE 4 RELATIVE LEGENDRE COEFFICIENTS. 2201800100052
COMMENT .GAMMA SPECTRA WERE CALIBRATED WITH A BE-7 SOURCE, 2201800100053
WICH EMITS THE SAME GAMMA-LINE. 2201800100054
.MEASUREMENTS WERE PERFORMED AT 44, 68, 91, 111 AND 2201800100055
139 DEGREES WITH RESPECT TO THE BEAM DIRECTION. 2201800100056
