Heavy Ion Collisions (HIC) represent a unique tool to probe the in-medium nuclear interaction in regions away from saturation and at high nucleon momenta. In this report we present a selection of reaction observables particularly sensitive to the isovector part of the interaction, i.e. to the symmetry term of the nuclear Equation of State (EoS) At low(More)
We investigate in detail the momentum dependence (MD) of the effective in medium Nucleon-Nucleon (NN) interaction in the isovector channel. We focus the discussion on transport properties of the expected neutron-proton (n/p) effective mass splitting at high isospin density. We look at observable effects from collective flows in Heavy Ion Collisions (HIC) of(More)
Myriocin is a potent inhibitor of serine-palmitoyl-transferase, the first and rate-determining enzyme in the sphingolipids biosynthetic pathway. This study developed, validated and applied a LC-MS/MS method to measure myriocin in minute specimens of animal tissue. The chemical analog 14-OH-myriocin was used as the internal standard. The two molecules were(More)
We present a detailed study of isospin dynamics in peripheral collisions at Fermi energies. We consider symmetric and mixed collisions of 124,112Sn isotopes at 35 and 50AMeV to study the isospin transport between the different reaction components (residues, gas and possibly intermediate mass fragments) and, in particular, the charge equilibration in the(More)
We review the present status of the nucleon effective mass splitting puzzle in asymmetric matter, with controversial predictions within both non-relativistic and relativistic approaches to the effective in medium interactions. Based on microscopic transport simulations we suggest some rather sensitive observables in collisions of asymmetric (unstable) ions(More)
