Evaporation residue products from reactions withKr86

Neutron multiplicities in inelastic collisions of132Xe with197Au

“…10 -2l S), whereas the lifetime for neutron emission is much longer on the average. Strong, although somewhat indirect support for this result comes also from a number of studies in which the mass and (or) charge lost by each fragment was deduced from detailed analyses of the heavy fragments alone [8][9][10][11]. The evidence discussed above tends to throw doubt on our earlier suggestion of pre-equilibrium effects in the system 132Xe+197Au [-1~.…”

Evaporation residue cross sections from the fusion of52Cr+110Pd

“…4 are obtained. This shape of the angular distributions is the most probable one as can be deduced from previous work [2,3]. To illustrate the margin of the uncertainty due to the eventually missing cross section at angles below 3 ~ Fig.…”

Proton transfer in quasi-elastic and deep-inelastic reactions in the systems86Kr on88Sr,90Zr and92Mo at energies close to the coulomb barrier

“…21 we indicate the quasi-elastic transfer cross sections with TKEL of 0_ 10 MeV (this represents twice the measured charge transfer cross section -assuming as an upper limit that single neutron transfer contributes the same amount). For the formation of a compound nucleus the limits in l can be inferred from the work of Plasil et al [37], who measured the evaporation residue cross section for a6Kr+9~ at 366MeV of 248_+75mb, which yields IcN = 55 + 9 h. The total fusion cross section of ~=497 mb from [37] gives a value for Ic~ =79 h, which is a theoretical result for a vanishing fission barrier. These values should be compared with the theoretical results of Table 8 These values compare rather favourably with critical angular momenta for fusion obtained in the analysis of the deep-inelastic events (Sect.…”
