INCOMPRESSIBILITY AND REACTIONS INDUCED BY WEAKLY BOUND PROJECTILE, ⁹Be

Abstract

Using a nucleon–nucleon force of the type M3Y-Reid and an additional repulsive interaction which simulates the incompressibility effects of the nuclear matter, we have examined the effects of the repulsive core modeling on the interaction potentials and complete fusion cross-sections for 9 Be + 124 Sn and 9 Be + 89 Y systems. The adjusted parameters of this repulsive force have been chosen in such a way that fully explains the properties of the nuclear matter in the region where the nuclear densities of the interacting nuclei completely overlap. The results of our studies reveal that accounting for this correction in the calculations of the total potentials leads to improvement of calculated cross-sections and affects on the complete fusion suppression at above barrier energies.

Nuclear matter incompressibility effect on the cross-section of fusion reactions with a weakly bound projectile

“…We also want to compare light target nuclei such as 29 Si and 27 Al with 209 Bi, 208 P b and explore whether or not complete fusion is also affected by the breakup process. This is an extension of our previous work [11] in which we conclude the trend of complete fusion suppression in reactions with light and heavy targets. This paper is organized as follows: a description of the theory employed to calculate the nuclear potentials by using the double folding (DF) model and simulation of incompressibility effects is given in Sec 2.…”

No-capture breakup and incomplete fusion reactions induced by stable weakly bound nucleus 9Be

“…[1][2][3][4][5][6][7][8][9][10] The reactions with exotic nuclei observed in the astrophysical processes are of particular importance in the nuclear physics research. Often these nuclei have such low binding energies and few-body cluster structures that they can easily be separated into two or more fragments in the reactions with other nuclei.…”

Role of Surface Energy Coefficients and Temperature in the Fusion Reactions Induced by Weakly Bound Projectiles

“…[17][18] It must be noted that the fusion suppression factor is a very sensitive quantity to the applied theoretical model. [6,19] Double folding [20] and Sao Paulo [21−22] potentials are two dominate approaches for parametrization of the nuclear interactions in such colliding systems. [6,13,19,23−24] Recently, the analysis of the CF channel of the reactions with weakly bound nuclei has also been performed using various versions of the proximity potentials.…”
