Nuclear transmutation has been reported by lots of experiments. The features of this phenomenon are the production of elements which shows fission-like distribution and their anomalous isotopic ratios or the selective Z and mass changes [1]. To analyze this phenomenon, the selective channel scission (SCS) model has been proposed and improved [2]. The SCS model is powerful and can predict the fi...

A brief description of our improvements and refinements that led from the CEM95 version of the CascadeExciton Model (CEM) code to CEM97 and to CEM2k is given. The increased accuracy and predictive power of the code CEM2k are shown by several examples. To describe fission and light-fragment (heavier than He) production, the CEM2k code has been merged with the GEM2 code of Furihata. We present so...

The Coulomb fission may take place in a reaction if the maximum excitation energy transfer exceeds barrier of either projectile or target nucleus. This condition is satisfied all reactions used for earlier blocking measurements time-scale except $$^{208}\hbox {Pb}~+$$ natural Ge crystal, where below measurement limit technique $$<1$$ as. Inclusion data analysis experiments leads us to interpret...

The total kinetic energy (TKE) of fission fragments for some heavy actinides is investigated and calculated using the scission point model. First, deformation parameters are obtained by fitting results to available experimental data. Then, behavior TKE distribution fission. This indicates that Usang model can better explaine heavier than californium Unik Also, value be approximated sum Coulomb ...

The cold(neutronless) fission of 252 Cf is studied in the frame of a molecular model in which the scission configuration is described by two aligned fragments interacting by means of Coulomb (+ nuclear) forces. The study is carried out for different distances between the fragments tips and excitation energies. For a given deformation, the fragment's total energy is computed via the constrained ...

Formation and stability patterns of silver dianionic and gold trianionic clusters are investigated with Penning-trap experiments and a shell-correction method including shape deformations. The theoretical predictions pertaining to the appearance sizes and electronic shell effects are in remarkable agreement with the experiments. Decay of the multiply anionic clusters occurs predominantly by ele...

The phenomenon of quantum tunneling is relevant in different areas of physics, from chemical reactions to nuclear fission and fusion below the Coulomb barrier. In most of the cases one has to deal with the tunneling of a complex object with internal degrees of freedom. In a one-dimensional model we investigate how an harmonically bound two-body system tunnels through an external gaussian barrie...
