Unitary-model-operator approach to Λ hypernuclei
نویسندگان
چکیده
A method is formulated for the description of lambda hypernuclei in the framework of the unitary-model-operator approach (UMOA). The method is applied to 17 Λ O. A lambda-nucleon effective interaction is derived, taking the coupling of the sigma-nucleon channel into account. The lambda single-particle energies are calculated for the 0s1/2, 0p3/2 and 0p1/2 states employing the Nijmegen soft-core (NSC), Jülich model-Ã (JÃ) and model-B̃ (JB̃) hyperon-nucleon potentials.

Amethod for a microscopic description of Λ hypernuclei is formulated in the framework of the unitary-model-operator approach. A unitarily transformed hamiltonian is introduced and given in a cluster expansion form. The structure of three-body-cluster terms are discussed especially on the Λ single-particle energy. The Λ single-particle energies including the threebody-cluster contributions are c...
متن کاملA particle-hole model approach for hypernuclei
A particle-hole model is developed to describe the excitation spectrum of single Λ hypernuclei and the possible presence of collective effects is explored by making a comparison with the mean-field calculations. Results for the spectra of 12 Λ C , 16 Λ O , 40 Λ Ca , 90 Λ Zr and 208 Λ Pb hypernuclei are shown. The comparison with the available experimental data is satisfactory. We find that coll...
متن کاملAb initio description of p-shell hypernuclei.
We present the first ab initio calculations for p-shell single-Λ hypernuclei. For the solution of the many-baryon problem, we develop two variants of the no-core shell model with explicit Λ and Σ(+),Σ(0),Σ(-) hyperons including Λ-Σ conversion, optionally supplemented by a similarity renormalization group transformation to accelerate model-space convergence. In addition to state-of-the-art chira...
متن کاملRole of deformation in the nonmesonic decay of light hypernuclei
We discuss the nonmesonic decay of deformed p-shell hypernuclei. The Nilsson model with angular momentum projection is employed in order to take into account the deformation effects. The nonmesonic decay rate decreases as a function of the deformation parameter, while the ratio of the neutronto proton-induced decay rates and the intrinsic Λ asymmetry parameter increase. We find that the deforma...
