概要

The intrinsic structure of ^<20>Ne with K^π=0^+ is investigated from the viewpoint of the structure change that it has a transient character from the shell-like to the α+^<16>O molecule-1ike structure. We set up a physical path of the structure change on the basis of the studies of the gap energy of the inversion doublet model and of the "deviation energy" from the α+^<16>O threshold. We give a microscopic alpha-particle model formulation to represent the structure change along this physical path in the framework of the generator coordinate method. We have obtained as the solutions of the Hill-Wheeler equation the shel11ike and molecule-like states with mutual interpenetration character. The essential features of the properties of the ground, 6.72 MeV 0^+ and 〜8.3 MeV 0^+ levels, are shown to be well understood from our approach.
