TITLE Angular distributions in neutron induced fission of 3051000100003
Th-232,natural uranium, Np-237 and Pu-239. 3051000100004
AUTHOR (S.Juhasz,M.Varnagy) 3051000100005

REFERENCE (S,ZFK-376,135,197812) 3051000100007
INC-SOURCE (CF252). 700 Micrograms 3051000100008
SAMPLE The natural uranium oxide (U3-O8) and natural thorium 3051000100009
oxide (Th-O2) samples of 10mm diameter and 1mg/cm2 3051000100010
thickness were prepared by sedimentation on an alum. 3051000100011
backing plate (0.3mm),and were covered by a VYNS-foil 3051000100012
of 0.01 mg/cm2. 3051000100013
The Np- and Pu- acetate samples of 1.5 mg/cm2 were 3051000100014
by a polyester foil of 10 micro-m thickness on a 3051000100015
plexiglass ring holder. 3051000100016
DETECTOR (TRD). Poly carbonate (Makrofol-E), for Th and Pu also 3051000100017
Makrofol-kg. 3051000100018
PART-DET (FF) 3051000100019
METHOD The Makrofol-E detectors had an angle of 30deg to the 3051000100020
direction of the incoming fragments. The tracks were 3051000100021
counted by optical microscope (magn.=300). 3051000100022
The Makrofol-kg foils had an angle of 90deg to the 3051000100023
fragment direction. The tracks were counted by the 3051000100024
'jumping spark counting' method (ref.: Varnagy+, Nucl. 3051000100025
Instr. Meth. 141,489 (1977)). 3051000100026
ANALYSIS A function of the form: 3051000100027
W(theta) = a0 + a2*(cos(theta)**2) 3051000100028
- where 'theta' is the angle in the center-of-mass 3051000100029
system - was fitted to the experimental angular 3051000100030
distribution by the least squares method. 3051000100031
The integral of W(theta) over spherical angles from3051000100032
0 to 180deg was normalized to the total fission cross- 3051000100033
section (monitor) to obtain the absolute angular-diff- 3051000100034
erential cross-sections and cosine coefficients. 3051000100035
ERR-ANALYS (ERR-S) Quoted uncertainties = statistical errors. 3051000100036
STATUS (APRVD),S.Juhasz on 800504 and 861216. 3051000100037
Numerical values of angular-differential cross sections3051000100038
as in fig.2 of ZFK-376,135, were supplied by author. 3051000100039
