Resumen

Using the Barmatz vibrating reed technique we have measured the Young's modulus of NbSe₃. An anomaly is observed at T₁ (142 K) but not at T₂ (58 K). Taken together with published specific heat data our results provide upper (lower) bounds for the anisotropy of the transition-temperature-stress-dependence at T₁ (T₂).
