SAMPLE To minimize the uncertainties in the projectile A058200100017
energies at each target foil, thinly stacked foils withA058200100018
only three targets were used in each stack. Aluminium A058200100019
foils of 6.85 mg/cm**2 were used as energy degraders A058200100020
and internal flux monitor. For measuring the cross A058200100021
sections of relatively short-lived nuclides, 1.0 A058200100022
mg/cm**2 thickness 197-Au deposited on Al spacer foils A058200100023
served as targets. To obtain measurable yields of A058200100024
long-lived residuals, self-supporting 46.6 mg/cm**2 A058200100025
thick 197-Au targets were used in the stack. Both the A058200100026
target and the degrader foils were 0F 99.99% purity. A058200100027
METHOD (STTA) See SAMPLE A058200100028
(ACTIV) The irradiation times were optimized according A058200100029
to half-lives of residual and the irradiations were A058200100030
performed in duplicate. A058200100031
(BCINT) The flux values were in good agreement with A058200100032
flux values obtained from monitor reactions. Their A058200100033
average was used to determine the cross sections. A058200100034
(GSPEC) The decay of characteristic gamma peaks was A058200100035
followed for more than five half-lives except for A058200100036
195-Au for which only two half-lives were followed. A058200100037

ANALYSIS (DECAY) A058200100045
ADD-RES (COMP) The excitation functions were analysed in terms A058200100046
of direct, pre-equilibrium and evaporation emissions. A058200100047
The two most commonly used models of pre-equilibrium A058200100048
reactions, the exciton and the hybrid models, have bothA058200100049
been used and compared. The choice of the initial A058200100050
exciton number, the role of the pre-equilibrium clusterA058200100051
and multiple nucleon emissions have been investigated. A058200100052
The direct emission of cluster are found to A058200100053
significantly affect the excitation functions of 197-HgA058200100054
and Au isotopes. A058200100055

COMMENT -By authors. For Tl-196 the metastable and ground-stateA058200600006
half-lives are comparable and isomer transition is A058200600007
4.5%. The gammas detected, however, are common to the A058200600008
decay of both Tl-196-m and Tl-196-g, thereby giving us A058200600009
sigma(m)+sigma(g). A058200600010
