“…The agreement is very good with the experimental data of Eisen et al [42] and of Lee et al [43]. The data of Dauk et al [44] are not consistent with our model and with the data at higher energies. A change of r c has no influence on the results below 25 MeV.…”

“…From bottom to top, the curves correspond to r c equal to 5.6 fro, 5.75 fm and 6.05 fro. Data are from [423 (g), [43] (x), [44] (o), [45] (n) and [46] (e) experimental data of the 160+ 2VAt fusion. We have determined a potential V(r) crossing at (to, V(ro) ) a parabola with its top at rS=8.93fm and V s = 15.73 MeV and a frequency corresponding to he% =5MeV (r0=7.25 fro, Vo=26.85MeV and a =0.52fm).…”

A barrier-penetration model for heavy-ion fusion, valid at all energies

We present a barrier-penetration model for heavy-ion fusion valid from the lowest energies available up to the largest energies for which the critical-radius picture is realistic. The parameters of the model are a critical radius and the parameters of a nucleus-nucleus interaction, whose form factor can be chosen freely. Fusion cross sections for a large number of systems, for which low-energy data exist, are fitted with a Woods-Saxon potential. Realistic parameters are obtained for the Coulomb barrier. Different applications and some limitations of the model are discussed.

“…III) we believe this extrapolation to have been done properly. Furthermore, in a recent investigation of the 2VAI+ 160 system where fusion cross sections have been measured by the 7-ray technique [6] as well as the direct observation of evaporation residues [7] good agreement in the data was found. The 7-ray technique does not allow to distinguish between fusion-like and nonfusion-like (i.e.…”

“…Instead of directly observing evaporation residues, which gets more difficult for lower bombarding energies, we chose to detect the secondary 7-ray transitions following particle evaporation. Although the direct population of residual groundstates cannot be measured, this 7-ray technique has been proven [6,7] to be a reliable means in the determination of o-fu s and hence be able to supplement data deduced through evaporation residue measurements.…”

Excitation functions of the one-and two-particle evaporation reactions 160(7Li, x~) and 160(7Li, xyT) , x, y=n, p, d, t and c~ have been measured in steps of 100-160 keV for ELi=4-10 MeV. All yield curves were rather smooth and could well be described by statistical model calculations taking into account one-and two-particle decays. No significant deviations of the total fusion cross section from the reaction cross section as given by the optical model were observed. A critical comparison is performed with earlier data of the same reaction taken at slightly higher energies where drastically reduced fusion cross sections were reported.
