Investigation of reactions cross-sections for targed halo nuclei using new evaluated semi-empirical formula

Liquid drop model although a well-defined surface, experimental research, Some of the neutrons or protons in the nucleus of certain illustrates goes outside of the drop surface. Leaky surface nucleons, condensed certain distance from the core is called in this case they form a halo of mist. The nuclei near the dripline, under certain circumstances, have been found to form a neutron or proton halo with a mass distribution that extends far outside the nuclear core. In this nuclei, since the seperation energy of the last nucleons becomes extremely small, the root mean square (rms) values of halos that extends far outside the core have been larger than core and matter radius of nuclei. This effect of the halo could have an important influence in that the increasing of the beta decay probability and the reducing of the logft values for halo nuclei. Tel et al. have suggested using the new experimental data to reproduce a new empirical formula of the cross-sections of the (n,p) reactions with dependent on asymmetry parameter s = N-Z/A and nuclear shell model. Tel et al. also obtained a new appropriate coefficient by using this formula for (n, 2n), (n,a), (n,d) and (n,t) reactions and Tel et al have succesfully applied the nucler reactions. In this project, the obtained formulas by Tel et al. have been applied the some 7Li, 11Li, 9Be and 14Be target halo nuclei for understanding the nuclear reactions and compaired with the experimental data.
