The triple point temperature of iodine

The paper aims at filling a gap in accurate data on the triple point temperature of iodine, I-2, whose experimental determination is found remarkably absent in the literature, by reporting accurate calorimetric results obtained in 1978 by a reliable Laboratory and so far unpublished, providing the ITS-90 value T-90 = 386.464 +/- 0.005 K (t(90) = 113.314 +/- 0.005 degrees C).
