1. 16. In-beam Study of Extremely Neutron deficient Nuclei Using the Recoil-Decay Tagging Technique

   Författare :Baharak Hadinia; Bo Cederwall; Patrik Regan; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear structure; Nuclear physics; Kärnfysik;

   Sammanfattning : The low-lying structures of the extremely neutron-deficient nuclei 106Te, 107Te, 110Xe, 170Ir and 172Au have been investigated experimentally. Prompt gamma rays emitted in fusion-evaporation reactions were detected by the Jurogam HPGe array. LÄS MER

3. 17. Statistical Investigations ofthe Emission Processes in Gamma-ray Bursts

   Författare :Zeynep Acuner; Felix Ryde; Judith Racusin; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gamma-ray bursts; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

   Sammanfattning : Physical emission mechanisms responsible for gamma-ray bursts (GRBs) remain elusive to this day, 50 years after their discovery. Although there are well studied physical models, their power to explain the observed data is a matter of debate. LÄS MER

4. 18. Experimental Studies of the Neutron Deficient Atomic Nuclei 94Ru, 95Rh and 172Pt via their Electromagnetic Properties : Du som saknar dator/datorvana kan kontakta Pär Olsson, [email protected] för information

   Författare :Aysegul Ertoprak; Bo Cederwall; Paul Garrett; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

   Sammanfattning : This thesis reports new results obtained from studies of the neutron deficient atomic nuclei 94Ru, 95Rh and 172Pt using two different experimental set-ups. In the first part, lifetimes of highly excited states in nuclei near the N=50 closed-shell (94Ru and 95Rh) were deduced from an analysis of the Doppler broadened transition lineshapes measured following the 58Ni(40Ca,4p) and 58Ni(40Ca,3p) fusion-evaporation reactions at the Grand Accelerateur National d'Ions Lourds (GANIL) accelerator complex situated in Caen, France.

5. 19. The role of knockout driven fragmentation in collision with isolated complex molecular systems

   Författare :Linda Giacomozzi; Henning Zettergren; Henrik Öström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Knockout processes; PAHs; HPAHs; porphyrins; fysik; Physics;

   Sammanfattning : This licentiate thesis covers results from collision induced dissociation (CID) experiments of Polycyclic Aromatic Hydrocarbons (PAHs), hydrogentated PAHs (HPAHs) and porphyrins. PAHs and HPAHs are believed to play key roles in the evolution of complex molecules in space, while porphyrins are essential for various functions in living organisms. LÄS MER

7. 20. Neutronics and Transient Analysis of a Small Fast Reactor Cooled with Natural Circulation of Lead : ELECTRA: European Lead Cooled Training Reactor

   Författare :Erdenechimeg Suvdantsetseg; Janne Wallenius; Yong Hee Kim; KTH; []
   Nyckelord :;

   Sammanfattning : In this thesis, neutronics and some relevant transient analyses of the European Lead-Cooled Training Reactor (ELECTRA) are analyzed. ELECTRA is a low-power lead-cooled fast reactor intended for training purpose. The design concept aims for the total nominal power of 0. LÄS MER
