    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; termodynamik; statistisk fysik; gravitation; relativitet; kvantmekanik; thermodynamics; Matematisk och allmän teoretisk fysik; Pseudo-scalar meson; Isospin Breaking; Chiral Perturbation Theory; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; statistical physics; Weak Interaction; Strong Interaction; kvantfältteori; High energy interactions; Kärnfysik; Nuclear physics; klassisk mekanik; quantum field theory; cosmic rays; Kosmisk strålning; högenergi; Elementarpartikelfysik;

    Abstract : Popular Abstract in Swedish Amplituden för fem olika processer av typen K -> 3 Pi och tre olika av K -> 2 Pi har beräknats i kiral störningsteori. Beräkningen har genomförts flera gånger med olika approximationer. Först används isospin-approximationen, men detta resulterar i diskrepanser mellan teori och experiment. READ MORE

  2. 7. Low and High Energy Ion Beams in Nanotechnology

    University dissertation from Avd. för Kärnfysik, LTH, Box 118, 221 00 Lund

    Author : Thomas Winzell; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion implantation; magnetic materials; ERDA; nanometer structures; Nuclear physics; MeV Ions; lithography; Kärnfysik; Fysicumarkivet A:2000:Winzell;

    Abstract : In this thesis, two ways of fabrication of nanometer-sized semiconductor features are presented. Low Energy Ion Implantation (LEII) has been used to create shallow (sub-50 nm) and laterally small (5 m m – 200 nm) features by 10 keV As+ doping of B background doped Si. READ MORE

  3. 8. Optimisation and Application of Intense High-Order Harmonic Pulses

    University dissertation from Department of Physics, Lund University

    Author : Lena Roos; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherent radiation; Optimisation; Multiphoton ionisation; Phase matching; Physics; Fysik; Atomic and molecular physics; Atom- och molekylärfysik; Laserteknik; Laser technology; High-power lasers; Short pulses; High-order harmonic generation; Short wavelength; Fysicumarkivet A:2001:Roos;

    Abstract : The high-order harmonics that are created in the interaction between an intense laser pulse (around 1014 W/cm2) and a gas medium are studied. The high-order harmonic radiation is a relatively new source of coherent radiation in the short wavelength range. READ MORE

  4. 9. Statistical and Dynamical Aspects of Intermediate Energy Nuclear Collisions

    University dissertation from Experimental High-Energy Physics

    Author : Roberta Ghetti; Lunds universitet.; Lund University.; [1997]
    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;

    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

  5. 10. Studies of Nuclear Matter under Extreme Conditions: Heavy-Ion Interactions at Ultra-Relativistic Energies
