Sammanfattning : This doctoral dissertation deals with a phenomenon that is often referred to in sports, but still poorly understood from a scientific angle: psychological momentum (PM). No consensus has been agreed on how to label this phenomenon, and other terms such as momentum or behavioural momentum (BM) are often used interchangeably. LÄS MER
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
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
Sammanfattning : The time scale of the dynamics in atoms and molecules varies from attoseconds (10-18) to picoseconds (10-12) depending on the size of the particles. To study such dynamics, ultrafast light pulses are needed to trigger and capture the reaction. One of the most direct methods consists in ionizing the system and observing the following response.
