Fusion of radioactive $^{132}$Sn with $^{64}$Ni

, 2007
Evaporation residue and fission cross sections of radioactive $^{132}$Sn on $^{64}$Ni were measured near the Coulomb barrier. A large sub-barrier fusion enhancement was observed.

Exact solution of Smoluchowski's equation for reorientational motion in Maier-Saupe potential

, 2014
The analytic treatment of the non-inertial rotational diffusion equation, i.e., of the Smoluchowski's one (SE), in a symmetric genuinely double-well Maier-Saupe uniaxial potential of mean torque is considered.

Comprehensive model for train-induced aerodynamic pressure on noise barriers: effects of bilateral layout and height

Engineering Applications of Computational Fluid Mechanics
Noise barriers play a crucial role in mitigating railway noise, with the aerodynamic pressure exerted by passing trains being a key factor in their structural design, particularly for those installed along high-speed railways. While previous studies have

Modeling of MoS2/Si heterostructure to study charge transfer dynamics

Nano Express
Here, we synthesized a MoS _2 /Si heterojunction device using a scalable approach involving DC sputtering coupled with sulfurization. The observed current–voltage characteristics unequivocally indicate a rectifying behavior at MoS _2 /Si heterointerface.

Numerical simulation of barrier height effect on output parameters, for a a-Si:H/nc-Si:H based solar cell

EPJ Web of Conferences, 2013
A numerical simulation by AMPS-1D (Analysis of Microelectronic and photonic structures) program has been carried out to examine the role of the front contact barrier heights φb0 , ITO/P nanocrystalline layer contact, on the performances of a-Si:H n-i-p ...

Theoretical studies of the potential surface for the F - H2 greater than HF + H reaction [PDF]

The F + H2 yields HF + H potential energy hypersurface was studied in the saddle point and entrance channel regions. Using a large (5s 5p 3d 2f 1g/4s 3p 2d) atomic natural orbital basis set, a classical barrier height of 1.86 kcal/mole was obtained at ...

Dynamic splitting of a Bose-Einstein Condensate

, 2000
We study the dynamic process of splitting a condensate by raising a potential barrier in the center of a harmonic trap. We use a two-mode model to describe the phase coherence between the two halves of the condensate.

Franz–Keldysh effect in β-Ga2O3 Schottky barrier diode under high reverse bias voltage

Applied Physics Express
The reverse-voltage dependence of a photocurrent in a Ni/ β -Ga _2 O _3 Schottky barrier diode was investigated under sub-bandgap monochromatic illumination with wavelengths ranging from 275 to 1200 nm.

Optimal height calculation and modelling of noise barrier

Mokslas: Lietuvos Ateitis, 2011
Transport is one of the main sources of noise having a particularly strong negative impact on the environment. In the city, one of the best methods to reduce the spread of noise in residential areas is a noise barrier.

Damping of Josephson oscillations in strongly correlated one-dimensional atomic gases

, 2018
We study Josephson oscillations of two strongly correlated one-dimensional bosonic clouds separated by a localized barrier. Using a quantum-Langevin approach and the exact Tonks-Girardeau solution in the impenetrable-boson limit, we determine the ...
