Abstract
The Tohsaki-Horiuchi-Schuck-Röpke (THSR) wave function has been successfully used for the studies of gaslike nature of clusters in various nuclei, including the so-called Hoyle state of and four states of . In standard cluster models, however, each cluster wave function has spin zero because of its spatial symmetry and antisymmetrization effect. Thus the noncentral interactions do not contribute, and this situation is the same in the THSR wave function. In this work, the spin-orbit contribution, which is found to be quite important at short distances, is taken into account in the THSR wave function by combing it with antisymmetrized quasicluster model (AQCM). The application to is presented. The multi-integration in the original THSR wave function is carried out by using a Monte Carlo technique, which is called the Monte Carlo THSR wave function. For the nucleon-nucleon interaction, the Tohsaki interaction, which contains finite-range three-body terms and simultaneously reproduces the saturation properties of nuclear systems, the scattering phase shift, and the size and binding energy of , is adopted.
