2. 1. Fragment Mass Distributions in Neutron-Induced Fission of 232Th and 238U from 10 to 60 MeV

   Author : Vasily Simutkin; Stephan Pomp; Franz-Josef Hambsch; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ADS; neutron-induced fission; intermediate neutron energies; fragment mass yield; Nuclear physics; Kärnfysik; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

   Abstract : Since its discovery, the phenomenon of nuclear fission is the object of extensive theoretical and experimental studies. However, we are still far from a complete understanding of the fission process. READ MORE

4. 2. Experimental Fission Studies at Intermediate Energies

   Author : Klas Elmgren; Ralf Nolte; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

   Abstract : A series of nuclear fission experiments have been performed in the intermediate energy range. The dynamics of the fission process have been studied by means of detection of neutrons emitted from compound nuclei formed by ion beams of protons, α-particles, and 12C-ions, all at a beam energy of 100 MeV.

5. 3. Statistical and Dynamical Aspects of Intermediate Energy Nuclear Collisions

   Author : Roberta Ghetti; Fysiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; excitation function.; subthreshold pions; pion production; neutron cross-talk; correlation function; interferometry; intermittency; phase transition; thermal scaling; reducibility; multifragmentation; Heavy ion collisions; intermediate energy; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1997:Ghetti;

   Abstract : Studies of intermediate energy heavy ion reactions have revealed the existence of a number of reducibility and thermal scaling properties in nuclear multifragmentation. In particular, the probability of emitting n-fragments is reducible to the probability of emitting a single fragment through the binomial distribution. READ MORE

6. 4. Investigations on Emission Sources in Proton-Nucleus and Nucleus-Nucleus Collisions

   Author : Johan Mårtensson; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; Fysik; Physics; correlation function.; fermion interferometry; t p and d p ratios; target mass dependence; pion angular distribution; pion excitation function; Heavy ion reactions; intermediate energy; cosmic rays; Kosmisk strålning; högenergi;

   Abstract : Emission sources in proton-nucleus and nucleus-nucleus collisions at intermediate energies have been studied. Pion excitation functions from the absolute threshold to 500 MeV have been measured with an ion beam of continuously varying energy with an energy resolution of 1 MeV. READ MORE

7. 5. Rotational Bands and Pairing Interaction in the Shell Model

   Author : Andrius Juodagalvis; Matematisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; Rotational bands; Shell model; Cranked Nilsson-Strutinsky; Pairing interaction; Backbending; Band termination; Proton-neutron pairing; Quadrupole electromagnetic moments and transition strengths; N=Z nuclei; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; Fysicumarkivet A:2000:Juodagalvis; termodynamik; statistisk fysik; kvantmekanik; relativitet;

   Abstract : One of the goals pursued in the present research was to understand the nuclear phenomena (such as rotational bands, their backbending and termination, deformation, pairing correlations, etc.) using different views provided by different nuclear models. READ MORE
