INFLUENCE OF THE SHELL EFFECTS ON THE CHARGE-DISTRIBUTIONS OF THE HEAVY-ION REACTION-PRODUCTS

Various approaches to calculate the coefficient of the transport equation describing the process of multinucleon transfer are analysed. It is shown that the expressions for transition probabilities containing the effects of the nuclear shell structure can be obtained if we do not use averaging of the matrix elements over many shell configurations. On this basis, in the framework of the model with the realistic single-particle scheme of levels the charge distributions of the reaction products in the collisions 52Cr + 181Ta, 51V + 197Au and 20Ne + 197Au are investigated. The role of the Coulomb interaction in a dinuclear system is discussed. It is shown that the Coulomb interaction increases the formation probability for very asymmetric configurations. © 1990 IOP Publishing Ltd.
