Description
This paper studies the time evolution of the isospin of two nuclei in presence of an exchange interaction. The diagonal terms of the Hamiltonian were evaluated from the mass formula, leaving as a free parameter the coefficient of the residual interaction (V). The time evolution was calculated at first and second order in V using a commutation algebra, through the solution of nine coupled linear equations corresponding to a Hilbert space. The isospins of colliding nuclei were utilized as stationary initial conditions. A Montecarlo simulation with the collision times and the impact parameters was used for comparing the results with the cross section experimental data. (Author)
Abstract (Spanish)
En el presente trabajo se estudia la evolucion temporal del spin isotopico de dos nucleos en presencia de una interaccion de intercambio. Las contribuciones diagonales del Hamiltoniano se evaluaron a partir de la formula de masas, dejando como parametro libre el coeficiente de interaccion residual (V). Usando un algebra de conmutacion se evaluo la evolucion temporal a primer y segundo orden en V, mediante la solucion de nueve ecuaciones lineales acopladas correspondientes a un espacio de Hilbert. Los spines isotopicos de nucleos colisionantes, se utilizan como condiciones iniciales estacionarias. Con el proposito de comparar los resultados con los datos experimentales de seccion eficaz, se utilizo una simulacion de Montecarlo con los tiempos de colision y con el parametro de impacto.
