“…Later, similar data were published for 8 B + 28 Si [2] at four energies well above the respective Coulomb barrier. In both experiments, a single type of evaporated charged particle was measured, and fusion cross sections were deduced from the respective experimental yields using statistical model calculations.…”

“…Indeed, it has been shown that, after reasonable data reduction, the reduced total reaction cross sections for 8 B + 58 Ni and for several neutron-halo systems fall on the same trajectory when plotted as a function of the reduced energy [9]. On the other hand, the 8 B + 28 Si system seems to present fusion suppression above the barrier [2], which would indicate a similar behaviour with respect to neutron-halo systems but an inconsistency with the trend observed for the heavier proton-halo system. (However, it should be pointed out that there is little data overlap between measurements of the two systems even when plotted versus reduced energy).…”

“…[2]), evaporation alpha particles rather than protons were measured and fusion cross sections were deduced using the evaporation code CASCADE ( [6]). The multiplicity issue that was favourable for the 8 B + 58 Ni system becomes a liability in this case because the respective alpha-particle multiplicity is low (M α ∼ 0.5).…”

Above-barrier fusion enhancement of proton-halo systems

Previously reported data for fusion of the 8 B + ( 58 Ni, 28 Si) systems are critically reviewed. New α particle data from the fusion of 8 B + 58 Ni also are reported, but the paper is mostly based on using realistic calculations of well established codes to reanalyze the previous data. The influence of breakup protons on the evaporation proton measurements for the heavier system is found to be small at all energies except for the lowest one measured, and corrections are made for this process. Possible model dependencies in the deduced fusion cross sections are investigated using three different evaporation codes. The data sets for the 58 Ni and 28 Si targets are shown to be consistent with each other and with fusion enhancement up to energies that are greater than the Coulomb barrier V b (E c.m. < ∼ V b + 1.5×hω). This limit corresponds to 6.2 MeV above the barrier for the 58 Ni target. An important difference with the behaviour of neutron-halo systems is thus confirmed.PACS numbers: 25.60. Pj ,
