  3. 2. Compton Scattering from the Deuteron at Low Energies

    Författare :Magnus Lundin; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Compton scattering; photonuclear reactions; deuteron; differential cross sections; 50-70 MeV; polarizability; tagged photons; Nuclear physics; Kärnfysik; Fysicumarkivet A:2002:Lundin;

    Sammanfattning : A series of three Compton scattering experiments on deuterium have been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 50 < Eg < 70 MeV tagged photons were scattered from a liquid deuterium target and detected simultaneously in three (10"x10") NaI detectors. LÄS MER

    Sammanfattning : Eta Carinae is a super-massive, super-luminous star. It is surrounded by a bipolar nebula, the "Homunculus", and several blobs of ejected gas which are the source of a complex emission-line spectrum. LÄS MER

  5. 4. Experimental and Computational Atomic Spectroscopy for Astrophysics : Oscillator strengths and lifetimes for Mg I, Si I, Si II, Sc I, and Sc II

    Författare :Asli Pehlivan Rhodin; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atomic Data; Astrophysics - Solar and Stellar Astrophysics;

    Sammanfattning : Atomic data such as oscillator strengths and wavelengths are important for astrophysical applications as they have a crucial role in determining abundances of specific elements in a star, a galaxy, or any object emitting radiation in the space. Stars in the Galaxy mostly keep the composition of the interstellar gas from which they were formed, therefore studying stellar abundances helps us understand how the Milky Way was formed and how it evolved.
