  1. 16. Atomic Electrons as Sensitive Probes of Nuclear Properties and Astrophysical Plasma Environments : A Computational Approach

    Författare :Asimina Papoulia; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2021:Papoulia; Computational atomic structure; Relativistic atomic theory; Transition probabilities; Abundance analysis; Landé g­-factors; Hyperfine structure; Nuclear quadrupole moments; Isotope shift; Field shift; Nuclear deformation;

    Sammanfattning : This thesis deals with the relativistic modeling of atoms and ions. To interpret the stellar spectra and gain more insight from astrophysical observations, the underlying processes that generate the spectra need to be well understood and described. LÄS MER

  3. 17. Resonant Interactions Between Nanoparticle Plasmons and Molecular Excitons

    Författare :Gülis Zengin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface-enhanced absorption; J-aggregates; Localized surface plasmon resonance; strong coupling; Rhodamine 6G; nanoparticles;

    Sammanfattning : Molecular plasmonics involves the study and applications of plasmonic metal nanostructures interacting with molecules. It has been a basis for development of fundamental understandings of light-matter interactions as well as of new technologies, including biological and chemical sensors and plasmon-enhanced spectroscopies.

  4. 18. Optical Characterization of GaN/AIGaN Quantum Well Structures

    Författare :Hamid Haratizadeh; Tatiana Shubina; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The III-nitride material family is particularly well suited for optoelectronic applications, e.g. as UV light emitters in future lighting solutions that are expected to replace the incandescent and fluorescent lamps in use today. LÄS MER

  5. 19. Comprehensive Gamma-Ray Spectroscopy of 62Zn and Studies of Nilsson Parameters in the Mass A = 60 Region

    Författare :Jnaneswari Gellanki; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High-spin gamma-ray spectroscopy; superdeformation; 62Zn; Cranked Nilsson-Strutinsky and effective alignments; Fysicumarkivet A:2013:Gellanki;

    Sammanfattning : Comprehensive experimental knowledge of the 62Zn nucleus has been obtained from the combined statistics of four different experiments. The Gammasphere Ge-detector array in conjunction with the 4pi charged-particle detector array Microball was used to detect the gamma-rays in coincidence with evaporated light charged particles.
