The total cross section of solid neon at 20 deg K and of solid argon at 77 and 20 deg K with monoenergetic neutrons between 3 x 10/sup -4/ and 2.6 x 10/ sup -3/ ev was measured in transmission study. With consideration of the condition that the theoretically estimated non-elastic scattering produces only a small contribution to the total cross section. the absorption cross section is obtained. Extrapolation by the l/v law to neutrons with v = 2200 m/sec (0.025 ev) gives for neon sigma /sub a/ (2200 m/sec) approx equal 0.03B plus or minus 0.007 b. With respect to the uncertainty in the knowledge of the scattering contribution, this value with the given error range should be regarded as an upper limit. For the incoherent scattering on neon an upper limit sigma /sub inoch/ < 0.1 b. For argon sigma /sub a/ = O.6l plus or minus 0.03 b is obtained in agreement with other results. (tr-auth)
