摘要：

The neutron-irradiation effects on C-60 fullerite powder were studied by positron lifetime spectroscopy. Below 0.5 ns, a single lifetime of 382 +/- 1 ps was found for the unirradiated annealed sample and two components were resolved after neutron irradiation with a dose of 2 x 10(16) n/cm(2). Possible origins of these components are briefly discussed.
