Description

The diffusion coefficient, cooling coefficient, and anisotropy of graphite were determined to be (2.19 ± 0.03) x 105 cm2 sec-1, (37.9 ± 4) x 105 cm4 sec-1, and 1.017 ± 0.008, respectively. The range of geometrical buckling was from 7 to 155 m-2. The values obtained are compared with published values. (authors)

Abstract (French)

Un programme experimental utilisant la methode de la source pulsee de neutrons a ete realise sur le graphite. La gamme des laplaciens couverte est de 7 m-2 a 155 m-2. Les resultats en sont presentes dans ce rapport: - coefficient de diffusion D0 = (2,19 ± 0,03) x 105 cm2 s-1 - coefficient de refroidissement C = (37,9 ± 4) x 105 cm4 s-1 - anisotropie du graphite (D parall./D perp.) = 1,017 ± 0,008. Ils sont compares aux valeurs deja publiees. (auteurs)
