Research interests

My major experimental work at this time is the investigation of the neutron capture cross section and the level structure of 99Tc, a long-lived radioactive waste product from reactors. Besides the basic physics interests, it's capture cross section is needed to plan how to burn it up in some future waste disposal facility. I'm using neutron capture measurements at the KFKI reactor in Budapest, as well as particle transfer experiments in Munich to get the needed information. I continue to have an interest in the level structure of the even-A tin isotopes 116,120,124Sn and in the buildup of light elements for nuclear astrophysics.
