ABS>The effective neutron cross section of Sm/sup 149/ was determined in three different reactor positions by measuring mass spectrometrically the amount of Sm/sup 150/ formed by neutron capture. Analysis of the results shows that the effective cross section of Sm/sup 149/ in a well-thermalized neutron spectrum of known temperature can be calculated to within plus or minus 2%. The cross section of Sm/sup 150/ in a thermalized spectrum at 50 deg C with r = 0.0015 is found to be 102 plus or minus 5 barns. (auth)
