By Jean-Patrick Connerade, Andrey Solov'yov

This publication offers a “snapshot” of the newest and critical advances within the box of cluster physics. it's a entire assessment according to contributions by way of the individuals of the second foreign Symposium on Atomic Cluster Collisions (Isacc 2007) held in July 19–23, 2007 at Gsi, Darmstadt, Germany. the aim of the Symposium is to advertise the expansion and exhange of clinical info at the constitution and homes of nuclear, atomic, molecular, organic and complicated cluster structures studied by way of photonic, digital, heavy particle and atomic collisions. specific awareness is dedicated to dynamic phenomena, many-body results happening in cluster structures of a distinct nature - those comprise difficulties of fusion and fission, fragmentation, collective electron excitations, part transitions, and so forth. either the experimental and theoretical points of cluster physics, uniquely put among nuclear physics at the one hand and atomic, molecular and sturdy country physics at the different, are mentioned.

Here, we give a short and concise review of several applications of the DNS model. e. the quasi-fission. 2. Hyperdeformed states Nuclei have excited states with the properties of molecular (or cluster) states. Such states could be the hyperdeformed (HD) states which are caused by a third minimum in the potential energy surfaces (PES) of the corresponding nuclei. ,7 that the third minimum of the PES of actinide nuclei belongs to a molecular configuration of two touching nuclei (clusters), which is a DNS configuration.

3. Nuclear structure with normal- and superdeformed bands The DNS model can be used to describe the normal-deformed (ND) and superdeformed (SD) bands of various nuclei. We applied this model to the structure of 60 Zn (Ref. 12 The observed strong collective dipole transitions between the excited SD band and the lowest-energy SD band in 150 Gd, 152 Dy, 190,194 Hg, 196,198 Pb and between the SD and ND bands in 194 Hg and 194 Pb indicate a decay out of pronounced octupole deformed states. 13 Configurations with large quadrupole and octupole deformation parameters and low-lying collective negative parity states are strongly related to a clustering describable with heavy and light clusters within the DNS model.

This Hamiltonian can be used to derive master equations for the probability PZ,N (t) to find the dinuclear system in a fragmentation with Z1 = Z, N1 = N and Z2 = Ztot − Z, N2 = Ntot − N . The master equations contain the oneproton and one-neutron transfer rates which depend on the single-particle energies and the temperature of the DNS where the occupation of the singleparticle states is taken into account by a Fermi distribution. The simultaneous transfer of more nucleons is neglected. The master equations include a term describing the quasi-fission with a rate obtained with the Kramers 10:53 42 Latest Advances in Atomic Cluster Physics 9in x 6in ch04 G.
