In this paper,the effect of the anisotropy diffusion on the growth of diffusion-limited aggregation(DLA) clusters is discussed.Our computer simulation results verify that DLA clusters grown with anisotropic diffusion rules have a striking overall diamond shape.A new anisotropic diffusion equation of particles is derived.The Hausdorff dimension of a two-dimensional DLA cluster in the anisotropic diffusion is calculated.The results show that the effective angle β eff =min(β ix ,β iy ).In addition,the generalized dimension D q of the anisotropic diffusion DLA is also discussed and an expression of the generalized dimension D q is obtained using the modified wedge model.

Infinite nuclear matter is assumed to be composed of an equal even number of protons and neutrons. The surface region of nuclear matter is replaced by an assembly of alpha-particles interacting through a potential composed of a strong short-range repulsion and a weak long-range attraction of the Gaussian form. The energy gap in nuclear matter and the effective mass of alpha particles have been calculated. The result shows that the energy gapΔ is more than 2 MeV but ≦5 MeV. The ratio of the effective mass m* to the free particle mass m of alpha-particles is always greater than unity and its maximum value is a little over 5. For an assembly of alpha-particles to be stable, it must be a dilute weakly interacting assembly. The net interaction must be repulsive and the nuclear density should be less than the saturation limit. The results have been compared with previous calculations.

The scattering cross sections of light by free electrons into the first two harmonics are evaluated neglecting the variation of the electron mass with velocity. It is observed that while the scattering cross section for the second harmonic is unaltered4 the intensity-dependent terms in the cross section for scattering into the principal mode are unexpectedly different.
