Differential cross-sections of 11B+α inelastic scattering at E(α) =
65 MeV leading to most of the known 11B states at excitation energies
up to 14 MeV were measured [1]. The data analysis was done using
Modified diffraction model (MDM) [2] allowing determining radii of
excited states. Radii of the states with excitation energies less than ∼
7 MeV coincide with the radius of the ground state with an accuracy
not less than 0.1 - 0.15 fm. This result is consistent with traditional
view on shell structure of low-lying states in 11B. Most of the observed
high-energy excited states are distributed among four rotational bands.
Moments of inertia of band states are close to the moment of inertia of
the Hoyle state of 12C. The calculated radii, related to these bands, are
0.7 - 1.0 fm larger than the radius of the ground state, and are close
to the Hoyle state radius. These results are in agreement with existing
predictions about various cluster structure of 11B at high excitation
energies.

Density functional studies of the electronic structure and catalytic properties of small bare and ligand-protected gold clusters
Kacprzak, Katarzyna Anna (University of Jyväskylä, 2010)In this thesis, bare and thiolate-protected gold nanoclusters and thiolated polymeric gold, silver and copper complexes are computationally studied by using density functional codes GPAW (grid projector augmented wave) ... -

Electronic, structural and chemical properties of gold clusters on ultra-thin oxide films
Frondelius, Pentti (University of Jyväskylä, 2009)Two decades ago, it was found that gold is catalytically active as clusters although it is known to be inert as bulk material. In the work presented in this thesis, density functional theory calculations have been applied ... -
