Nucleon exchange properties of theE/A=8.5 MeVGe74+

Abstract

Mass and charge distributions have been measured for damped projectile-like fragments in the reaction ' Ge+' 'Ho at 8.5 MeV per nucleon bombarding energy. Coincidences were measured between Zand A-identified projectile-like fragments and angle-correlated heavy reaction partners in order to derive the primary mass distribution for projectile-like fragments.

“…Furthermore, Monte Carlo simulations employing the actual non-Gaussian shape of the elastic line yield values of 1.0 and 5.0 for this variance for energy losses of 40 and 170 MeV, respectively. The above values are significantly higher than one would obtain based on the original evaluations[17] postulating a Gaussian resolution function (0.5 and 4.3 from 40 and 170 MeV, respectively). It should be stressed that the finite-resolution effects under discussion scale quite accurately with the variance of the resolution function and not with its FWHM As the actual resolution functions are non-Gaussian, their FWHM do not provide a proper measure of the quality of the experimental setup.…”

Transport properties of isospin asymmetric nuclear matter using the time-dependent Hartree-Fock method

“…The absence of quantal decay (other than evaporation of single-particle wave-functions) and transitions prevents us from dynamically calculating the secondary and further fragments. It is expected that the primary fragments will undergo various processes to approach the β −stability line in time [16]. However, assuming that it is statistical in character, the deexcitation process can be calculated with programs like GEMINI [85,86] provided realistic inputs can be obtained.…”

“…The methods described in Refs. [16,87] were applied to obtain the centroids for the Z and N distributions of postevaporative projectile-like fragments. Similar to previous studies [16] in Fig.…”

“…[16,87] were applied to obtain the centroids for the Z and N distributions of postevaporative projectile-like fragments. Similar to previous studies [16] in Fig. 11 we show the evolution of the centroids of the nuclides distributions in the N versus Z plane for different energy-loss bins for the 78 Kr+ 208 Pb system.…”

“…For example, collisions at Fermi energies give access to contact times which are short enough to induce only a partial charge equilibration [12] and thus can be used to determine equilibration times [13]. Alternatively, charge equilibration has also been studied with deep inelastic collisions at lower energies, but with large isospin asymmetry in the entrance channel [14][15][16]. To reveal possible systematic trends requires both theoretical and experimental studies with a wide variety of projectile and target combinations which are expected to become available at current and future radioactive ion-beam (RIB) facilities [17].…”
