The neutron-proton bremsstrahlung process (np→npγ) provides a unique and sensitive probe of meson exchange currents in the nucleon-nucleon interaction. The differential cross section for this process is being measured at LANSCE. A liquid hydrogen target is exposed to the intense, pulsed neutron beam from the WNR facility, and the scattered neutrons and recoil protons are observed in coincidence at angles between 20° and 36° on opposite sides of the beam. Measurement of the neutron and proton energies allows full kinematic reconstruction of each event. The resulting angular distributions of the bremsstrahlung photons will be compared with the predictions of a theoretical calculation. © 2000 American Institute of Physics.

    The mass surface of nuclei close to the doubly magic nuclide [sup 78]Ni is calculated by two methods. The first relies on the multiparticle shell model based on an effective interaction and a mean nuclear potential. The second employs the concept of so-called "magic crosses" and enables us to...

    We have investigated p-n junctions on a silicon device fabricated on a (100) surface using photoemission electron microscopy (PEEM). We show that different doping levels for the p-and n-doped regions in the surface give rise to a contrast in the PEEM images. The contrast is due to the change in...

    This paper discusses the gravitational radiation that accompanies the formation of a rotating protoneutron star. Mainly large-scale entropy inhomogeneities develope inside the star. As a result, bubbles of hot nuclear substance are formed, and convective motions arise: bubbles of hot neutron...
