    Författare :Tanvir Sayed; [2024]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. The Commissioning of a Pixelated Charge-particle Detector : for High-sensitivity Measurements of Hydrogen

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Joacim Stenlund; Aram Himelius; [2023]
    Nyckelord :;

    Sammanfattning : The Tandem Laboratory at Uppsala University, a national research infrastructure forworld-leading materials analysis, has a long history of performing hydrogen measurementusing NRA (Nuclear Reaction Analysis). This project intents to diversify the infras-tructure for hydrogen measurement by investigating the feasibility of an advanced ERCS(Elastic Recoil Coincidence Scattering) system, enabling finer detection limits.

  5. 4. Optimization of Gammasphere Data Following the Nuclear Reaction 36Ar + 24Mg → 60Zn∗

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Paul Böhm; [2023]
    Nyckelord :re-calibration; Gammasphere; 54Fe; Physics and Astronomy;

    Sammanfattning : The experiment at Argonne National Laboratory aimed to study the fusion-evaporation reaction following the collision of a high-energy particle beam of 36Ar with a stationary target of 24Mg. This paper outlines the creation and implementation of an automated re-calibration procedure for the high-purity Germanium detectors comprising the Gammasphere array used for γ-ray spectroscopy in this experiment.

  7. 5. Becoming by Buying : A qualitative study about Brandengagement in self-concept (BESC) in the pre-purchase stage

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Företagsekonomi

    Författare :Philip Brunkes; Lina Johansson; [2023]
    Nyckelord :Fast-Fashion; Brand Engagement in Self-concept; Pre-purchase stage; Self- concept; Consumer decision making process; Self-congruity;

    Sammanfattning : Fast fashion brands provide consumers with constantly available opportunities to update,not only their wardrobes, but themselves. As our identities have become a constant projectto work on, consumption of fast fashion involves the possibilities of trial and error ofpersonal development. LÄS MER
