The most favored model to produce the radiation of GRBs calls for internal shocks within a relativistic outflow of plasma, produced by accretion onto newly born few solar masses black hole. This would produce a neutron rich fireball (Beloborodov 2003, astro-ph/0210522). We investigate the possibility that neutrons, decaying sizably before and during the GRBs phase, heat the protons to relativis...

A study of the association of serotonine with 5'-AMP by PMR spectroscopy is described. The association constants obtained from the chemical shift of non-equivalent protons show considerable variation outside experimental error, a fact which wTas reported by several authors. To support the suppositon that small amounts of complexes of different stoichiometry, — which in general can hardly be det...

Relativistic neutron-loaded outflows in gamma-ray bursts are studied at their early stages, before deceleration by a surrounding medium. The outflow has four components: radiation, electrons, protons and neutrons. The components interact with each other and exchange energy as the outflow expands. The presence of neutrons significantly changes the outflow evolution. Before neutrons decouple from...

We examine whether protons and deuterons in a crystal of KH(0.76)D(0.24)CO(3) at 300 K are particles or matter waves. The neutron scattering function measured over a broad range of reciprocal space reveals the enhanced diffraction pattern anticipated for antisymmetrized macroscopic states for protons (fermions). These features exclude a statistical distribution of protons and deuterons. Raman s...

We propose that a measurement of the number of protons and antiprotons in the hemisphere opposite a large transverse momentum proton can distinguish between two important models for large transverse momentum processes. The Parton Jet Model (PJM), where the underlying mechanism is assumed to be quark-quark scattering, is characterized by a surplus of protons over antiprotons in the jet opposite ...

In muon accelerators, muons are produced by impacting high energy protons onto a target to produce pions. The pions decay to muons which are eventually accelerated. A significant background of protons and electrons are generated that deposit heat in superconducting materials and activate the machine. In this paper we describe a two-step particle selection scheme: a chicane to remove the high mo...

We study properties of the proton component of neutron star matter for a number of realistic nuclear models. Protons which form a few percent admixture tend to be localized in potential wells corresponding to neutron matter inhomogeneities created by the protons in the neutron medium. We calculate the energy of the Wigner-Seitz cell enclosing a single localized proton. The neutron background is...

The ordering of protons has been observed at a new storage ring, S-LSR, at Kyoto University. Abrupt jumps in the momentum spread and the Schottky noise power were observed for protons for the first time at a particle number of approximately 2000, upon applying electron cooling with electron currents of 25, 50, and 100 mA. The transition temperature was 0.17 and 1 meV in the longitudinal and tra...

By means of a particle-in-cell (PIC) simulation, we study the interaction between uniform magnetized ambient electron–proton plasma at rest and an unmagnetized pair plasma, which inject one simulation boundary with mildly relativistic mean speed temperature. The magnetic field points out plane. injected expels piles it up its front. It traps electrons drags them across protons. An electric grow...

We investigate the origin of the nonthermal X-ray emission from the Galactic ridge in the range 10−200 keV. We consider bremsstrahlung of subrelativistic cosmic ray protons and electrons as production processes. From the solution of the kinetic equations describing the processes of particle in situ acceleration and spatial propagation we derive parameters of the spectra for protons and electron...
