  "abstract": "In order to explore the 4 \\alpha-particle condensate state in 16O, we solve a full four-body equation of motion based on the 4 \\alpha OCM (Orthogonality Condition Model) in a large 4 \\alpha model space spanned by Gaussian basis functions. A full spectrum up to the 0_6^+ state is reproduced consistently with the lowest six 0^+ states of the experimental spectrum. The 0^+_6 state is obtained at about 2 MeV above the 4 \\alpha breakup threshold and has a dilute density structure, with a radius of about 5 fm. The state has an appreciably large \\alpha condensate fraction of 61 %, and a large component of \\alpha+12C(0_2^+) configuration, both features being reliable evidence for this state to be of 4 \\alpha condensate nature.",
