Higher harmonics and spectrum of O+ states of nucleus 12C

By method of hyperspherical functions the properties of O+ states of the nucleus 12C are calculated taking into account all the states with K=Ksub(min) and K=Ksub(min)+2 among the states with the most symmetric Young schemes. It has been shown that with the expanding of the basis main breathing characteristics and expected low-lying excited states change imperceptibly. Obtaining results point to the necessity of taking into account some higher excitations and alongside to the slow resemblance of hyper--spherical expansion for the tasks of such type
