“…The experimental results are compared with two "reference" lines. The solid line represents the stability valley; it was calculated using the following formula, taken from Reference [26] U in lead at 1⋅A GeV [8] with the beta-stability line [26] and the prediction of EPAX [27] for the fragmentation of 197 Au and for the fragmentation of 56 Fe. The measured mean values from the fragmentation of 197 Au in hydrogen at 800⋅A MeV [20] and of 56 Fe in hydrogen at 414⋅A MeV [28] are shown in addition.…”

Isotope yields of heavy residues produced in collisions of 238 U with lead at 1⋅A GeV show indications for a simultaneous break-up process. From the average N-over-Z ratio of the final residues up to Z = 70, the average limiting temperature of the break-up configuration at freeze out was determined to T § 0H9 XVLQJ WKH LVRVSLQ-thermometer method. Consequences for the understanding of other phenomena in highly excited nuclear systems are discussed.

“…In the upper part of the Fig. 16 it can be seen that the fission fragments produced in the reaction 208 P b + p (500 A MeV) are mainly neutron-rich while the fragments resulting from the fission of the system 208 P b + p (1000 A MeV) are nearer the valley of stability (black line, average values taken from [53]) and even on the neutron-deficient side. The data for 208 P b + d (1000 A MeV) are even more neutron-deficient.…”

The isotopic distributions and recoil velocities of the fission fragments produced in the spallation reaction 208 P b + p at 500 A MeV have been measured using the inverse-kinematics technique, a lead beam onto a liquid-hydrogen target, and the high-resolution spectrometer FRS at GSI. The shapes of the different distributions are found in good agreement with previously published data while the deduced total fission cross-section is higher than expected from existing systematics and some previous measurements. From the experimental data, the characteristics of the average fissioning system can be reconstructed in charge, mass and excitation energy, and the average number of post-fission neutrons can be inferred. The results are also compared to different models describing the spallation reaction. The intranuclear cascade code INCL4 followed by the de-excitation code ABLA is shown to describe reasonably well the evolution of the isotopic distribution shapes between 500 and 1000 A MeV.

A new mass table calculated by the relativistic mean field approach with the state-dependent BCS method for the pairing correlation is applied for the first time to study r-process nucleosynthesis. The solar r-process abundance is well reproduced within a waiting-point approximation approach. Using an exponential fitting procedure to find the required astrophysical conditions, the influence of mass uncertainty is investigated. R-process calculations using the FRDM, ETFSI-Q and HFB-13 mass tables have been used for that purpose. It is found that the nuclear physical uncertainty can significantly influence the deduced astrophysical conditions for the r-process site. In addition, the influence of the shell closure and shape transition have been examined in detail in the r-process simulations.
