Description
We have studied the α-condensed states of 16O and 20Ne based on a microscopic α-cluster model. This was performed by introducing a Monte Carlo technique for the description of the THSR (Tohsaki Horiuchi Schuck Roepke) wave function, which is called the ''virtual THSR'' wave function. Earlier microscopic calculations pointed out the possibility of the existence of four-α-cluster condensed states. Here, in addition to studying the four-α case, we also studied the case of five-α particles, for which the states are shown to be stable around the threshold energy even after taking into account the coupling effect between normal cluster states with 16O+α configurations
