Abstract

The wave functions of the ground states for 8,10Be which are obtained from the Monte Carlo shell model (MCSM) are investigated. A method to define an intrinsic state in the MCSM is discussed. The appearance of two-α-cluster structure in 8Be and the property of the valence neutrons in 10Be are also discussed.

Summary

Introduction

In the large region of the nuclear chart, the shell-model picture is essential to understand the properties of nuclear structure. For the mass number A ≤ 14, shell-model calculations without assuming an inert core have been performed. At such light mass region, cluster structure plays an important role. In its analysis of A = 8 nuclei, the two-α-cluster shape emerges a priori from the density distribution This achievement is important for the shell-model calculation without the inert core. The size of the model space which is tractable in the shell-model calculation has been increased due to the development of parallel computers and methodology of shell-model calculations EPJ Web of Conferences we show the density profiles of wave function obtained in the no-core-MCSM calculation.
