One of the recent discoveres in nuclear Physics is the existance of Halo nuclei .Therefore, halo nuclei are very weakly-bound exotic states of nuclear matter in which the outer one or two valence nucleons (usually neutrons), and a nuclear core with normal nuclear density is surrounded by a region of dulite nuclear matter, referred to as the neutron halo. Such nuclei occur from light to heavy masses and have been the subject of a alarge number of theoretical studies to try and understand them.

       The optimization calculations are made to find the optimum properties of combined quadrupole lens which consists of electrostatic and magnetic lens.  The optical properties are computed, where both the focal length and the magnification are determined.  Both chromatic and spherical aberration coefficients are reduced to minimum values and the achromatic aberration are found for many cases.This calculation are achieved with the aid of transfer matrices method and using both rectangular and bell-shaped models of field distribution, where the path of charged

The present project aims to the analyses and model the auto-navigation process. Putting mathematical model for aeroplane autonavigation requires an understanding to the aeroplane mobility in atmosphere,
