A famous and long-standing problem so-called the “mysterious” 0+ state in 16O is discussed with a single scheme, a 12C plus four-nucleon five-body model. The wave function is expressed in terms of explicitly correlated Gaussian functions. Preliminary results show that the energy levels are in good agreement with experiment. A welldeveloped 12C+α cluster structure appears in the first excited 0+ state, whereas the ground state has shell model like structure.
