The recently observed resonance ({ital E}{sub c.m.}=32.5 MeV) in the 0{sup +}{sub 2}{minus}0{sup +}{sub 2} channel of {sup 12}C+{sup 12}C collisions is predicted to be a weakly coupled structure of two three-{alpha}-particle states (0{sup +}{sub 2} state of {sup 12}C). At the same time a well-known resonance ({ital E}{sub c.m.}=29 MeV) in the 0{sup +}{sub 1}{minus}0{sup +}{sub 2} channel is explained as of three {alpha} particles plus {sup 12}C core structure. The band crossing model is shown to be valid also for inelastic scatterings to {alpha}-cluster states. A strong resonance is predicted in the 3{sub 1}{sup {minus}}{minus}0{sup +}{sub 2} channel in the same energy region. A relation to the linear chain configuration of six {alpha} particles is discussed.
