Isotopic scaling and the symmetry energy in spectator fragmentation.
Isotopic effects in the fragmentation of excited target residues following collisions of 12C on (112,124)Sn at incident energies of 300 and 600 MeV per nucleon were studied with the INDRA 4pi detector. The measured yield ratios for light particles and fragments with atomic number Z < or = 5 obey the exponential law of isotopic scaling. The deduced scaling parameters decrease strongly with incre...

متن کاملGRAPESPH with Fully Periodic Boundary Conditions: Fragmentation of Molecular Clouds
A method of adapting smoothed particle hydrodynamics (SPH) with periodic boundary conditions for use with the special purpose device Grape is presented. Grape (GRAvity PipE) solves the Poisson and force equations for an N-body system by direct summation on a specially designed chip and in addition returns the neighbour list for each particle. Due to its design, Grape cannot treat periodic parti...
متن کاملA preliminary model for isotopic fractionation
20 The aim of this paper is to assess the Zn isotopic variabilty in feed materials and in 21 combustion by-products collected from three different coal-fired power plants and to 22 develop a generalized model that accounts for the Zn isotopic fractionation occuring 23 during coal combustion processes. Partitioning of Zn between combustion residues and 24 the isotopic composition of feed materia...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
