摘要：

We present the first measurements of magnetisation and Raman light scattering on alpha l- NaV2O5 single crystals. Below 34 K, we observe a pronounced isotropic decrease of the susceptibility indicating the opening of a spin gap. The transition temperature is slightly field dependent. Raman experiments reveal a crystallographic distortion at the transition. Our results clearly establish alpha' - NaV2O5 to be the second inorganic spin-Peierls system.
