Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

We have used a new electrostatic storage ring to study the
dynamics of clusters, in particular fullerenes. With injection from an
electrospray source also biomolecules in the gas phase can be investigated
in the ring. In some cases the results are of direct relevance for our
understanding of the behaviour of the molecules in their natural
environment, in water solution or embedded in a protein. As an example,
recent results for fragmentation of adenosine monophosphate nucleotides will
be discussed, which give information about the stability of DNA under
irradiation with UV light.
