Abstract
In this paper we have calculated the energy spectrum of 12C isotope in twocluster models 3 α cluster model and 8Be + α cluster model We use the modified Yukawa potential for interaction between the clusters and solve the Schrödinger equation using Nikiforov–Uvarov method to calculate the energy spectrum Then we increase the accuracy by adding spinorbit coupling and tensor force and solve them by perturbation theory in both models Finally the calculated results for both models are compared with each other and with the experimental data The results show that the isotope 12C should be considered as a three α cluster and the modified Yukawa potential is adaptable for cluster interactions
