SAMPLE A self supporting thorium target of thickness 2.5 A072900100009
mg/cm2 was covered with a 0.0025 cm aluminium catcher A072900100010
foil to collect the recoiling fission products. A072900100011
DETECTOR (HPGE) A072900100012
FACILITY (VDGT,3INDTRM) The BARC-TIFR PELLETRON accelerator A072900100013
METHOD (SITA) See SAMPLE A072900100014
(BCINT) An electron-suppressed faraday cup A072900100015
(EXTB) Beam current on the target was in the range of A072900100016
10 to 15 Na (particle). A072900100017
(ACTIV) The irradiation time was 30 minutes for the A072900100018
investigation of short lived fission products and 4.5 A072900100019
hours for the long-lived ones. A072900100020
(GSPEC) For short irradiation, the sample was followed A072900100021
for three days, while for the long irradiations the A072900100022
sample was counted for a period of three months. A072900100023
The purity of the gamma-lines for the different fissionA072900100024
products was ascertained by following their half-lives.A072900100025

COMMENT -By author. The measured cross-section correspond to A072900200021
the products recoiling in the forward direction plus aA072900200022
small fraction of the backward recoiling products A072900200023
stopped in the thorium metal foil. These small A072900200024
contributions were corrected for the recoil ranges of A072900200025
the fission products in thorium metal. A forward- A072900200026
to-backward (F/B) ratio equal to one was used to A072900200027
convert the measured yields into total yields. The A072900200028
assumption of F/B ratio of unity will not affect the A072900200029
final yields by more than 10% in view of the measured A072900200030
F/B ratio of 1.1 for 16-O induced fission of 238-U. A072900200031
