Abstract: The main goal of the project is to improve the theoretical description of
the dynamics of binary quantum systems, a key issue in the physics of
synthesis and decay properties of heavy and superheavy elements, a hot topic
in the world, in which European scientists play a leading role (element 110
was named Darmstadtium in 2003). In order to explain the individual
properties of the initial and final participants and their interaction
during the formation and decay, an approach allowing to follow continuously
the quantum system evolution will be used. It is based on a further
improvement of the most advanced two center shell model developed in our
group. A finite-depth Woods-Saxon potential well, allowing to obtain levels
in the continuum, will be employed to develop a new type of two center shell
model. The dynamics involves calculation of the action integral and its
minimization after introducing the multidimensional hydrodinamical inertia
tensor and the potential barrier according to the macoscopic-microscopic
method. Also the coupled-channels approach will be used to compute the total
width, angular distribution and the fine structure of the low-lying states
of emitted fragments. Charge-density variation properly taken into account
in the single particle model and the extension of the residual pairing
interaction during the overlapping stage may be mentioned among the new
features of the model. The obtained results will be used by experimentalists
to choose the most favourable pair of partners for the production of
superheavy compound systems and to estimate the halflife against fission,
cluster emission, alpha-decay and proton radioactivity. Proton emission will
be studied by solving numerically the time-dependent Schroedinger equation.
As a multidisciplinary aspect, one should mention the potential
applicability of the two center shell model to study the nano-science of
atomic clusters and some binary and ternary molecules . By taking into
account the expertise of participating scientiststo, their international
cooperations with prestigious experts from Europe, USA and Japan, the
objectives of the present project have high chances to be achieved. Key
members of our team are very experienced as coordinators and participants in
the European Commission Centre of Excellence IDRANAP from IFIN-HH and other
international projects.
