The radial thermal expansion coefficient αr of pure and Xe-saturated bundles of singlewalled carbon nanotubes has been measured in the interval 2.2-120 K. The coefficient is positive above T = 5.5 K and negative at lower temperatures. The sample was prepared by compacting a CNT powder such that the...
