The thermal expansion of fullerite C₆₀ has been measured in the temperature range 2-9 К A compacted fullerite sample with a diameter of about 6 mm and height of 2.4 mm was used. It was found that at temperatures below - 3.4 К the linear thermal expansion coefficient becomes negath re. At temperature...
