摘要：
A mean field study of triatomic molecules in the vibron model is carried out. Analytical solutions for the mean fields are found, and shape-phase transitions in the model are investigated utilizing these solutions. The Majorana interactions are shown to play an essential role in driving the phase transition from linear to bent shape. Results presented here will facilitate realistic studies of bent molecules within the symmetry-breaking approach. (C) 1999 Elsevier Science B.V. All rights reserved.
