1. 1. 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.

3. 2. Nuclear Structure near the Proton Drip-line: A Search for Excited States in 62Ge

   Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Dalia Farghaly; [2022]
   Nyckelord :nuclear physics; nuclear structure; proton drip-line; excited states; germanium; fusion-evaporation reaction; experimental nuclear physics; gamma sphere; gamma spectroscopy; HPGe detectors; data analysis; Physics and Astronomy;

   Sammanfattning : An experiment to study mirror symmetry in the mass A = 60 region was performed at the Argonne National Laboratory (ANL) in 2020. The fusion-evaporation reaction 40Ca + 24Mg → 64Ge* at a beam energy of 106 MeV was used to populate excited states in 62Ge. LÄS MER

4. 3. Digitised charged-particle discrimination in CsI detector signals

   Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Mats Bror Linus Persson; [2022]
   Nyckelord :Microball; Gammasphere; pulse-shape discrimination; scintillator; charge-comparison method; cosine similarity; exotic nuclei; fusion-evaporation reaction; Argonne National Laboratory; Physics and Astronomy;

   Sammanfattning : This work is aimed at improving the discrimination of protons and α particles in digitised signals from CsI(Tl) scintillators. This has been achieved using pulse-shape discrimination, wherein the shape of the pulses is used to learn which particle is detected. LÄS MER

5. 4. Analysis of triple gamma coincidences for studies of the level structure of nuclei in the 100-Sn region

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Kärnfysik

   Författare :Ludvig Hallberg; [2017]
   Nyckelord :;

   Sammanfattning : In this master thesis a thorough analysis of data collected in an experiment performed at the JYFL accelerator laboratory in Finland using a reaction with a 47-Ti beam on a 58-Ni target is presented. The prompt emitted gamma rays from the fusion-evaporation products were detected in the gamma-ray spectrometer JUROGAM II, while the recoils were detected in the GREAT spectrometer. LÄS MER
