  1. 1. Decay Chains of Fast Alpha Emitters in the Actinide Region

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Tanvir Sayed; [2024]
    Keywords : alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

    Abstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

  3. 2. Climate Change Coverage and the Performance of Green and Brown Equities

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Anton Flygare; Fredrik Tingets; [2023]
    Keywords : climate change; green investments; equities; sustainability; news; Business and Economics;

    Abstract : Climate change has emerged as one of the world’s most pressing issues, a development that has prompted investors to shift their focus accordingly, catalysing a significant increase in green investments. This study is set against this backdrop, focusing on the performance of portfolios of European firms classified as low or high emission intensity – green or brown respectively – during an eight-year period, from January 2010 to June 2018.

  4. 3. Is there a carbon emission-return relation? Exploring the existence of a carbon emission return relation in the Swedish stock market

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Gustaf Kaddik; William Lundell; [2023]
    Keywords : emission premium; emission alpha; carbon emissions; emission intensity; stock returns;

    Abstract : We use portfolio sorting and Fama-Macbeth regressions to investigate the potential relation between carbon emissions and stock returns in the Swedish stock market, a country with stringent carbon regulations and taxes. We research the Swedish stock market between 2010-2019 and do not find evidence of such a relationship. READ MORE

  5. 4. Dead layer determination for the new implantation detector of the LUNDIUM decay station

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Eleftheria Kosta; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The Nuclear Structure Group in Lund, focuses on nuclear spectroscopy of decays of rare isotopes. A new decay station, called LUNDIUM, is currently being built, which will involve silicon and germanium detectors for the study of these nuclei. This thesis focuses on the characterization of one of the new silicon detectors, the implantation one. READ MORE

  6. 5. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Gaurav Senthil Kumar; [2022]
    Keywords : QSO; Quasar; Black Hole; AGN; Active Galactic Nuclei; DLA; Damped Lyman Alpha; C II; [C II]; H I; Sightline; HST; X-shooter; Spectroscopy; Echelle Spectroscope; Hyperfine transition; Hyperfine; Physics and Astronomy;

    Abstract : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. READ MORE
