Phonon scattering by interstitial atotns in graphite has been studied by measur-ing the o-axis thermal conductivity of electron-irradiated pyrolytic graphite in thetenaperature range of 5 to 80 K. The electron irradiation was perfornaed at tena-peratures around 80 K. The relaxation tinae of p'honon scattering by intc:rstitialatoms is inversely proportional to tlae phonon frequency; that is, r-"=Bco, where7l?=1.lpxlO-' for 1 ppm of interstitial atouaas. 0hauages in the elastic constantc.. due to irradiations have also been deterznined tl?rough the thernaal condxuctivitydata analysis.
