Calculation of the He-3(He-3, 2p)He-4 AND H-3(H-3, 2N)He-4 astrophysical S-factor at low energies
We have calculated the cross sections for the charge symmetric reactions He-3(He-3,2p)He-4 and He-3(He-3,2p)He-4 at sub-Coulomb energies in the potential model. Good agreement with the experimental data is obtained. The ...

Analysis of Li-8(alpha, n)B-11 below the Coulomb barrier in the potential model
The reaction Li-8(alpha, n)B-11 is of interest in inhomogeneous big bang nucleosynthesis. A distorted wave Born approximation calculation employing folding potentials is presented for energies below the Coulomb barrier. ...
The production of precision silicon micromachined non-spherical particles for aerosol studies
A variety of accurately defined non-spherical particles have been produced in silicon dioxide and polycrystalline silicon using the process of silicon micromachining. The particles are of lengths 3μm, 4.5μm, 7.5μm, and ...
The characterisation of airborne particles by analysis of spatial light scattering profiles
An instrument has been developed to investigate the potential characterisation of airborne particles, with particular reference to shape and size, by analysis of the spatial intensity distribution of scattered light. In ...
Airborne particle shape and size classification from spatial light scattering profiles
A new instrument for the study of airborne particles is described. The instrument incorporates a laminar flow sample delivery system which constrains airborne particles to traverse a focussed laser beam in single file. ...
Detection of photospheric Zeeman features and cyclotron emission lines in V834 CEN in a low state
Simultaneous spectroscopic and polarimetric observations of the AM Herculis system V834 Cen during a low state of accretion are reported. The polarization data show a reversal in the sign of the circular polarization when ...
