2-(3-Hydroxybenzylamino)acetic acid
There are two independent 2-(3-hydroxybenzylamino)acetic acid molecules, C9H11NO3, in the asymmetric unit of the title compound. The dihedral angle between the benzene rings of the two independent molecules is 58.12 (4)°. The crystal packing is stablized by intermolecular O—H⋯O and N—H⋯O hydrogen bonds
Diffuse emission of TeV Neutrinos and Gamma-rays from young pulsars by Photo-meson interaction in the galaxy
It's generally believed that young and rapidly rotating pulsars are important
sites of particle's acceleration, in which protons can be accelerated to
relativistic energy above the polar cap region if the magnetic moment is
antiparallel to the spin axis(). To obtain the
galactic diffusive neutrinos and gamma-rays for TeV, firstly,we use Monte
Carlo(MC) method to generate a sample of young pulsars with ages less than
yrs in our galaxy ; secondly, the neutrinos and high-energy gamma-rays
can be produced through photomeson process with the interaction of energetic
protons and soft X-ray photons () for single pulsar, and these X-ray photons come from the
neutron star surface. The results suggest that the diffusive TeV flux of
neutrinos are lower than background flux, which indicated it is difficult to be
detected by the current neutrino telescopes.Comment: 11pages,6figures. arXiv admin note: text overlap with arXiv:0812.1845
