Entrance-channel potentials in the synthesis of the heaviest nuclei
نویسنده
چکیده
Entrance-channel potentials in nucleus-nucleus collisions, relevant for the synthesis of superheavy elements, are systematically studied within a semi-microscopic approach, where microscopic nuclear densities of the colliding spherical or deformed nuclei are used in semi-classical expressions of the energydensity functional. From experimental data on fusion windows evidence is found that the existence of pockets in the entrance-channel potentials is crucial for fusion. Criteria for the choice of best collision systems for the synthesis of superheavy elements are discussed. PACS. 25.60.Pj Fusion reactions – 25.70.Jj Fusion and fusion-fission reactions

Contribution of Somatic and Dendritic SK Channels in the Firing Rate of Deep Cerebellar Nuclei: Implication in Cerebellar Ataxia
Introduction: Loss of inhibitory output from Purkinje cells leads to hyperexcitability of the Deep Cerebellar Nuclei (DCN), which results in cerebellar ataxia. Also, inhibition of small-conductancecalcium-activated potassium (SK) channel increases firing rate f DCN, which could cause cerebellar ataxia. Therefore, SK channel activators can be effective in reducing the symptoms of this disease, ...

Floor intake is one of the best options for diverting mountain rivers' flow. Determination of discharge diverted in different conditions of flow in main channel is one of the main objectives for intake under rack floor condition. Gradient and shape of grid rod floor can affect the discharge deviated. In this experiment, placement and gradient of grid rods and also their effects on the discharge...
متن کاملStudying the effect of sediment control structures of sill on sediment entrance into the intake with different angles
Using lateral intake is a method of floodwater diverting. In arid and semi-arid areas, floodwatercontains a large amount of sediment that will be carried in to the intakes and it causes a reduction inchannel conveyance. Sediment is almost transported into the intake and it is settled in the upstreamside of lateral channel. Sedimentation in this zone reduces the conveyance of lateral channel and...

The fusion and evaporation residue cross sections for the 50Ti+249Cf and 54Cr+248Cm reactions calculated by the combined dinuclear system and advanced statistical models are compared. These reactions are considered to be used to synthesize the heaviest superheavy element. The 50Ti+249Cf reaction is more mass asymmetric than 54Cr+248Cm and the fusion excitation function for the former reaction i...
متن کاملSimulation of flow pattern in intake by using a numerical model
Lateral intake is a structure constructed next to a main channel to divert part of the flow within the channel. The separated area of the flow in the entrance of intake channel has no effect on flow discharge while reduces the effective cross-sectional area of the intake, as well as the bed load, which enters the intake due to low velocity flow deposits in this area. Thus, knowing the dimension...
