The astrophysical (stellar) reaction rates were fitted as in previous works (Thielemann et al 1987;Rauscher & Thielemann 2000) in the common REACLIB seven parameter form, and these parameters are also tabulated.…”

“…2, different mass-and fission barrier predictions were utilized to test the sensitivity stemming from different underlying models. The models used are: masses taken from the Finite Range Droplet Model (FRDM) by Möller et al (1995), the Extended Thomas-Fermi with Strutinsky Integral (ETFSI) model by Aboussir et al (1995), and the Thomas-Fermi (TF) model of Myers & Swiatecki (1996); fission barriers are taken from the ETFSI (Mamdouh et al 2001) and TF (Myers & Swiatecki 1999) models. It should be emphasized that the ETFSI masses employed here (http://www-astro.ulb.…”

Neutron-induced reaction rates, including fission and neutron capture, are calculated in the temperature range 10 8 ≤ T (K) ≤ 10 10 within the framework of the statistical model for targets with the atomic number 84 ≤ Z ≤ 118 (from Po to Uuo) from the neutron to the proton drip-line. Four sets of rates have been calculated, utilizing -where possible -consistent nuclear data for neutron separation energies and fission barriers from Thomas-Fermi (TF), Extended Thomas-Fermi plus Strutinsky Integral (ETFSI), Finite-Range Droplet Model (FRDM) and Hartree-Fock-Bogolyubov (HFB) predictions. Tables of calculated values as well as analytic seven parameter fits in the standard REACLIB format are supplied. We also discuss the sensitivity of the rates to the input, aiming at a better understanding of the variations introduced by the nuclear input.

“…In the same way the macroscopic components of fission barriers for the heavier nuclei from Rn to Th were obtained, but in this case only very asymmetric combinations were considered in the SM analysis. These data are shown in Figure 6 together with the predictions of different models [30,[44][45][46][47] and tabulated values [48] for the macroscopic barriers (bottom panels). Shell corrections calculated in [17] and those obtained in the framework of the present analysis (see Section 2) could be also compared (upper panels).…”

Abstract. Production of the heavy and heaviest nuclei (from Po to the region of superheavy elements close to Z=114 and N=184) in fusion-evaporation reactions induced by heavy ions has been considered in a systematic way within the framework of the barrier-passing model coupled with the statistical model (SM) of de-excitation of a compound nucleus (CN). Excitation functions for fission and evaporation residues (ER) measured in very asymmetric combinations can be described rather well. One can scale and fix macroscopic (liquid-drop) fission barriers for nuclei involved in the calculation of survivability with SM. In less asymmetric combinations, effects of fusion suppression caused by quasi-fission (QF) are starting to appear in the entrance channel of reactions. QF effects could be semi-empirically taken into account using fusion probabilities deduced as the ratio of measured ER cross sections to the ones obtained in the assumption of absence of the fusion suppression in corresponding reactions. SM parameters (fission barriers) obtained at the analysis of a very asymmetric combination leading to the production of (nearly) the same CN should be used for this evaluation.

Abstract. The possibility of heavy particle radioactivity (heavier clusters) in ground state decays of 287−289 115 parent nuclei, resulting in a doubly magic daughter around 208 Pb is analyzed using Preformed Cluster Model (PCM) with choices of spherical and quadrupole deformation (β 2 ) having "optimum" orientations of decay products. The behavior of fragmentation potential and preformation probability is investigated in order to extract better picture of the dynamics involved. Interestingly, the potential energy surfaces obtained via the fragmentation process get modi¿ed signi¿cantly with the inclusion of deformation and orientation effects, which in turn inÀuence the preformation factor.
