Research Interests

I am a physicist working with the A1 and A2 collaborations in Mainz, Germany, the MAX Laboratory in Lund, Sweden and the Jefferson Laboratory in Virginia, USA where I am involved in experiments in Hall A and Hall B. My main research interest is studying the character of the nucleon-nucleon interaction in nuclei from measurements of photon induced two-nucleon knockout. The measurements allow the study of violent nucleon-nucleon collissions which are not included in the usual mean field description of the nucleus. These interactions originate from the short range repulsive part of the NN interaction and from tensor forces, both interesting and poorly understood phenomena. In the short range interactions heavy meson exchange and/or quark-gluon degrees of freedom may come into play. These short range and tensor interactions are of fundamental importance and without their contribution all nuclei would simply break up into individual protons and neutrons.
I am also involved in measurements of the structure of the nucleon and in measuring the matter distribution of nuclei. Recently I have been involved in measuring the low energy neutron doses received by patients in radiotherapy. For more details of the research I am involved with see the list of publications or the list of experiments under analysis.
