The Investigations Of Knockout Reaction Based On The Independent α Cluster Model

Knockout reaction is a kind of effective method of studying the interior structure of the atomic nucleus. This paper is on the basis of forefathers' studies,striking on the a cluster model knockout reactions. We have adopted two kinds of optics potentials:the first is the commonly used Woods-Saxon potential V}VS(R);the second is the optics potential Vcln(R) derived from the independent a cluster model. This paper has also adopted two kinds of the relative cluster wave functions in addition:one is the wave function through solving Sclirodinger equation;the other is wave function Ll(R) derived by Li Qingrun etc. on the basis of the independent a cluster model. In order to obtain the potential VJt(R),we have simulated the elastic scattering experimental data in which the energy respectively is 146MeV 104MeV 80.7Mev 65MeV 54. IMeV and the data in which the energy respectively is 166MeV 139MeV,104MeV,90MeV. On the basis of two wave functions and two optical potentials above mentioned,we have investigated a series of knockout reactions: Through the comparing of two wave functions and two optical potentials,we find that two a cluster relative vave functions which contribute to the energy sharing results of the reaction sections are very well,especially for the ;that the received spectroscopic factors used VfM(R) are better than that used ;that the former not only suits to the elastic scatterings but also to the knockout reactions;that the a cluster of knockout reactions are its local behaviors ofsurface. And we further testify that the distorted influences are not neglected if the incidence energies are not very high,but can be used the plane wave impulse approximate method and neglect the effects of the distorted influences if the incident energies are high enough.
