Theoretical study of the stability of charged metal clusters

Objective




Metal clusters are presently the object of intensive research.
Recently, the dissociation of multiply charged clusters through Coulomb explosion, binary fission and evaporation has been
observed. Our project is a large-scale theoretical study of the collective aspects of the evaporation and fission decay channels. We use temperature-dependent density functional theory and
the jellium approximation. With Hartree-Fock and perturbation expansion techniques, we test the local density approximation as basic ingredient. We apply methods earlier developed in
nuclear fission theory to calculate deformation energies, inertial parameters, and barrier penetration probabilities for both
axially and nonaxially deformed clusters. The dynamical response of a charged cluster in an external time-dependent
electric field is treated within the Random phase Approximation.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.
