Thermal control in spacecraft will be increasingly important as the spacecraft grows smaller and more compact. Such spacecraft with low thermal mass will have to be designed to retain or reject heat more efficiently. The ...
Un-doped, Tb3+ as well as Yb3+ doped ZnO nanocrystals with different concentrations of RE3+ (Tb3+, Yb3+) ions were successfully synthesized via sol-gel method to produce rare earth activated zinc oxide nanophosphors. The ...
In this work we calculate the binding energies and root-mean-square radii for A−body
nuclear bound state systems, where A ≥ 3. To study three−body systems, we employ
the three−dimensional differential Faddeev equations ...
A two-dimensional integrodi erential equation resulting from the use of potential harmonics
expansion in the many-body Schr odinger equation is used to study ground-state
properties of selected few-body nuclear systems. ...
Magnetic ordering of dopants in diamond holds the prospect of exploiting diamond’s unique
properties in the emerging field of spintronics. Several transition metal defects have been
reported to order ferromagnetically ...
The atomic physics relevant to gaseous nebulae is critically examined using modelling
software with particular emphasis on radio recombination lines (RRLs). The
theoretical spectral line intensities can be deduced if we ...
Electromagnetic processes induced by electron scattering off few-nucleon systems are theoretically
investigated in the non-relativistic formalism. Non-relativistic one-body nuclear current
operators are used with a ...
The problem of fitting a material property of the earth to a certain model by
analysing a returned seismic signal is investigated here. Analysis proceeds with
methods taken from the theory of inverse problems. Seismic ...
A new and very general method was developed for calculating the charge and spin-resolved electron tunnelling in type-II heterojunctions. Starting from a multiband k.p description of the bulk energy-band structure, a multiband ...
Although the merits of practical work in physics are often questioned, it remains part of
physics curricula world-wide. In distance education the incorporation of practical work into
the curriculum is considerably ...
The double hypernuclear systems are studied within the context of the
hyperspherical approach. Possible bound states of these systems are sought
as zeros of the corresponding three-body Jost function in the complex ...
This work is aimed at the understanding of the dynamical behavior of hydrogen
in diamond. The investigation was carried out using Transverse Field muon Spin
Rotation (TF-SR) and the Longitudinal Field muon Spin Relaxation ...
1720 MHz OH masers have been detected towards a number of supernova remnants (SNRs) at the shock interface where the SNR slams into the interstellar medium. Models indicate that these masers are shock excited and can only ...
Bound state systems consisting of three nonrelativistic particles are numerically
studied. Calculations are performed employing two-body and three-body forces as
input in the Hamiltonian in order to study the role or ...
We are concerned with the quantum inverse scattering problem. The corresponding
Marchenko integral equation is solved by using the collocation method together with
piece-wise polynomials, namely, Hermite splines. The ...
The long-standing problem of possible formation of metastable states in collisions
of the eta-meson with atomic nuclei is revisited. The two-body eta-nucleon interaction
is described by a local potential, which is ...
Radioactive decay of nuclei via emission of ??-particles is studied using three different
theoretical approaches, viz: the quasi-bound state wavefunction approach (QSWA), the
superasymmetric ??ssion model (SAFM) and the ...
The three-body bound state problem is considered using configuration-space Faddeev equations within the framework of the total-angular-momentum representation. Different
three-body systems are considered, the main concern ...
