TITLE -Cross section measurement for Hg-199(n,n')Hg-199-m 2182900100007
reaction from 0.78 to 6.3 MeV. 2182900100008
FACILITY (VDG,2JPNJAE) 5.5 MV Van de Graaff 2182900100009
INC-SOURCE (D-D) A deuterium target supplied by the 2182900100010
Radiochemical Centre was used. By cooling the target 2182900100011
with a jet of air, no appreciable decrease in neutron 2182900100012
yield was observed for 20 hr with a beam current up 2182900100013
to about 2 micro-A in a 20 mm2 spot. 2182900100014
(P-LI7) A Li target was prepared by the vacuum 2182900100015
evaporation method of natural lithium fluoride LiF 2182900100016
onto a Ti backing foil. The thickness, of the lithium 2182900100017
fluoride layer is about 500 mu-g/cm2 which corresponds2182900100018
to an energy loss of about 60 keV for 2 MeV protons. 2182900100019
SAMPLE .Mercury sulphate powder pressed into discs of 2182900100020
20 milli-m diameter and about 3 milli-m thick, 2182900100021
weighed to 1.0 milli-g. 2182900100022
.Samples sandwiched by indium foils of the same 2182900100023
diameter and of 0.5 milli-m thickness. 2182900100024
METHOD (ACTIV) Activation techniques. 2182900100025
DETECTOR (HPGE) A high purity germanium detector of diameter 2182900100026
42.5 milli-m and length 59.9 milli-m used to measure 2182900100027
gamma activity. 2182900100028
(TELES,SIBAR,CSICR) A proton recoil telescope 2182900100029
consisting of a polythene radiator in front of a 2182900100030
proton detector: 2182900100031
* above 5 MeV neutron energy a silicon surface 2182900100032
barrier detector 2182900100033
* below 5 MeV a CsI(Tl) detector. 2182900100034
PART-DET (DG) Decay gammas 2182900100035
(N) neutrons 2182900100036
CORRECTION .Self absorption of the gamma rays in the Hg sample 2182900100037
were calculated by a monte carlo method. The self 2182900100038
absorption in the indium foils was less than 1%. 2182900100039

COMMENT .The different values obtained for the cross 2182900200022
section agree within error limits except at 2182900200023
0.78 MeV neutron energy. In this case the 2182900200024
measurements normalised by the indium monitor 2182900200025
are more reliable, since an insufficient 2182900200026
number of recoil protons were counted. 2182900200027
