Abstarct: The main objective of this research work is to obtain a suitable model in a non-microscopic approach to study the interactions of alpha and nucleon clusters and to calculate the proposed radius, energy and potential coefficients for several baxse and excited alignments in 14O and 14C isotopes and a suitable equation. Designed to describe the nuclear structure. We did the calculations of the energy values and the coefficients of potential and radius with two discrete potentials of Holsen and second order Yukawa and the second potential of Yukawa and second order Yukawa. The Schrödinger equation is used to investigate and perform the calculations and the NU parametric method is used to solve it analytically. Both calculations were performed by two potentials and a three-particle model and we achieved significant results.
