1. Isomeric yield ratio measurements with JYFLTRAP : In quest of the angular momentum of the primary fragments
Sammanfattning : In this thesis, isomeric yield ratios of twenty nuclides produced in the fission of natU and 232Th by protons at 25-MeV and natU by high-energy neutrons were studied. The experiments were performed at the IGISOL-JYFLTRAP facility at the University of Jyväskylä. LÄS MER
2. All-Fiber System for Photonic States Carrying Orbital Angular Momentum : A Platform for Classical and Quantum Information Processing
Sammanfattning : The protection of confidential data is a fundamental need in the society in which we live. This task becomes more relevant when observing that every day, data traffic increases exponentially, as well as the number of attacks on the telecommunication infra-structure. LÄS MER
3. Transfer of Angular Momentum in Astrophysical Discs
Sammanfattning : In this thesis a study of astrophysical discs, with emphasis on galactic discs, is presented. The frictional force acting on a small satellite galaxy, moving on a co-planar circular orbit in a galactic disc, is shown to be only weakly dependent on the velocity dispersion and the self-gravity of the disc.

4. Probing the Drip-Lines through Momentum Distributions
Sammanfattning : About a decade ago it was found that nuclei in the vicinity of the neutron drip-line under certain circumstances develop very extended valence neutron distributions, a phenomenon today known as halo states. The recent development of radioactive nuclear beams has provided us with a perfect tool for investigating these particular nuclei. LÄS MER
5. Momentum exchange between light and nanostructured matter
Sammanfattning : An object's translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system's motion. LÄS MER
