Abstract

• Nucleon single-particle energy states in ordinary nuclei and Λ single particle energy states in Λ-hypernuclei are compared to study the role of Λ particle in nuclear medium. So, we examined the single particle energy state in Λ- hypernuclei C 12 Λ and ordinary nuclei C 12 6 . In our calculation, in order to get the single particle energy levels of C 12 Λ and C, 12 6 we used the phenomenological Woods-Saxon Λ-core nucleus potential and nucleonnucleus potential including spin-orbit term. Gaussian basis wave function is used in our consideration systems.
