Based on a recent experimental finding which may suggest the existence of a tri-nuclear molecular structure before the cold ternary fragmentation of 252Cf takes place, we solved the eigenvalue problem of a certain class of vibrations which are very likely to occur in these molecules. These oscillations are the result of the joined action of rotations of the heavier fragments and the transversal...

Beams of accelerated exotic neutron-rich nuclei allow access to little known regions of the nuclear landscape that are important both structurally and for r-process nucleosynthesis. We propose to increase the radioactive beam capabilities of the ATLAS accelerator facility by the installation of a new source of ions to provide beams of shortlived neutron-rich isotopes. These isotopes will be obt...

Present theoretical investigations aim to explore the fusion characteristics of various isotopes Z=120 within relativistic mean-field (RMF) formalism. We predict most suitable projectile-target combination for synthesis element Z=120. The microscopic nucleon-nucleon R3Y interaction and RMF density distributions targets projectiles are used calculate nuclear potential using double folding approa...

A concrete room with a single-legged maze was constructed in order to simulate a medical accelerator room. Gamma and neutron measurements were performed along the maze with a) a 252 Cf source and b) a tungstenmoderated Cf source placed inside the room. The measurements were repeated after placing an inner borated polyethylene door of varying thickness (2.54 -10.16 cm) at 2 different locations. ...
