Abstract

A new method is introduced to study three-body clusters. Triangular configurations with D3h{\cal D}_{3h} point-group symmetry are analyzed. The spectrum, transition form factors and B(Eλ)B(E\lambda) values of 12^{12}C are investigated. It is concluded that the low-lying spectrum of 12^{12}C can be described by three alpha-particles at the vertices of an equilateral triangle, but not as a rigid structure. Large rotation-vibration interactions, Coriolis forces and vibration-vibration interactions are needed. Other interpretations, such as the harmonic oscillator and a soft deformed oscillator with SO(6) hyperspherical symmetry, appear to be excluded by electron scattering data.
