A new method is introduced to study three-body clusters. Triangular configurations with D 3h pointgroup symmetry are analyzed. The spectrum, transition form factors, and B(EΞ») values of 12 C are investigated. It is concluded that the low-lying spectrum of 12 C can be described by three alphaparticles 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.

Quantum-mechanical calculations of three-body contributions to the dipole polarizability in linear and triangular He3 clusters are presented. Account is taken of electron correlation. For short distances, three-body terms can be large, dependent upon geometry, and although for distances greater than
