/* '6' To measure activities of radioactive products of the target
and monitors. The efficiency versus energy curve of the
detector was determined experimentally using standard gamma-ray
point sources with known strength, 152Eu, 133Ba, 241Am. 60Co
and 137Cs. Efficiency is also calculated using the EGS4 Monte
Carlo Code [Nelson et al, 1985]. */
/* Experimental Method:
- Stacked target irradiation (Stack was assembled from
molybdenum, copper and aluminium as Cu-Al-Mo and 10 groups were
set together in an aluminium holder for irradiation.)
- Energy degradation by foils (Energy degradation along the stack
was determined using the computer program SRIM-2002 [J.F. Ziegler
et al., The stopping and range of ions in solids, Pergamon, New
York, 1984.] assuming the incident energy was 70 MeV.)
/* Analysis:
- Decay curve analysis (Two or more radionuclides emitted
gamma-rays having very close energies, which were difficult to
separate by the graphical analysis of the multicomponent decay
curve, were analyzed using the difference in half-life of the
nuclides by plotting the photon emission rate as a function of
time.)
/* Gamma energies given (except 90Tc and 90Nb) are obtained by private
communication with authors. */
