The total errors are 7 to 10% in various3260500100025 angles 3260500100026 (ERR-S) Only statistical error given in data tables 3260500100027 The other major sources of error are as follows: 3260500100028 (ERR-1) Non-uniform distribution of the collimated 3260500100029 neutron beam etc. (5%); 3260500100030 (ERR-2) Neutrons small angle scattered from the 3260500100031 surface of the collimator.
