25 Jun 2013 | | Abstract: | The thick-target recoil properties of 90 nuclides, varying from $^{24}$Na to
$^{198}$Au, formed in the interaction of 4.4-GeV deuterons with $^{197}$Au,
have been measured for the first time in the literature, up to our knowledge,
in order to study the systematics of their variation with product mass. The
products forward-to-backward ratios ($F/B$) exhibit the different behavior,
which depends upon the mass region of the reaction products. There was an
evidence supportive of the existence of several different mechanisms in the
reaction studied. The results are analyzed by the two-step model of high-energy
reactions and discussed in terms of the different reaction mechanisms,
spallation, fission and fragmentation. Fission contributes appreciably to the
formation of products in the mass region 65 $leq$ A $leq$ 120 amu. The
kinematic features for deuteron-induced reaction have been compared to those
for reactions of energetic protons with gold. The relation between forward
momentum and mean deposition energy allowed to estimated the mean excitation
energy for the different mass range of the reaction products. It was concluded,
that a few sources having different excitations can take part in the formation
of residual nuclei. | | Source: | arXiv, 1306.6027 | | Services: | Forum | Review | PDF | Favorites | |
