We have studied three-alpha states around {sup 40}Ca based on a microscopic alpha-cluster model. Quite recently experimental evidence for such states has been obtained. This study was performed by introducing a Monte Carlo technique for the description of the Tohsaki-Horiuchi-Schuck-Roepke (THSR) wave function, which is called the 'virtual THSR' wave function. The three-alpha-cluster state around {sup 40}Ca has an energy below the Coulomb-barrier top energy with a spatial extension comparable to the second 0{sup +} state of {sup 12}C.
