Firstly, the n-p capture 125 1451 21 reaction (MT=102), and its inverse, deuteron photo- 125 1451 22 disintegration, were a part of the analysis, rather than added 125 1451 23 later as before. The analysis used a new method for including 125 1451 24 photon channels in R-matrix theory [1], which gave a better 125 1451 25 description of the E1 transitions, in particular. The data for 125 1451 26 these reactions are mostly integrated and differential cross 125 1451 27 sections, but some information about polarizations was also 125 1451 28 included. The thermal capture cross section was taken to be 125 1451 29 332.0 mb, as was the recommendation from preliminary data 125 1451 30 testing. Good agreement was obtained with recent cross-section 125 1451 31 measurements [2,3] by astrophysical groups in the 20-550 keV 125 1451 32 range, as well as with earlier measurements that had been done 125 1451 33 mostly as photo-disintegration experiments at energies below 14 125 1451 34 MeV. 125 1451 35 The new analysis includes several additional measurements of the 125 1451 36 total cross section (MT=1). The evaluated cross section 125 1451 37 deviates at most by about -0.5% around 10 MeV from that of 125 1451 38 ENDF/B-VI. The estimated uncertainty of the MT=1 cross section 125 1451 39 is given at 2 MeV steps in the following table: 125 1451 40 En Uncert.

A new measurement of the angular 125 1451 56 distribution at 10 MeV [4], plus corrections to earlier data at 125 1451 57 14 MeV, moved the back-angle asymmetry in the 10-14 MeV range to 125 1451 58 values that lie between those obtained for ENDF/B-V and ENDF/B- 125 1451 59 VI. The addition of the latest value of the thermal coherent 125 1451 60 scattering length [5] had the interesting effect of reducing the 125 1451 61 "zero-energy" scattering cross section somewhat to agree 125 1451 62 perfectly with an earlier measurement by Houk [6], and disagree 125 1451 63 with the later, more precise, value of Dilg [7]. The 125 1451 64 covariances for MT=2 will be added later, but the uncertainties 125 1451 65 on the integrated cross section should be similar to those 125 1451 66 listed above for the total cross section. 125 1451 67 125 1451 68 REFERENCES 125 1451 69 125 1451 70 [1] G.

[1] The major channel in this case is elastic 125 1451 86 scattering, often labeled also as ''n-p'' scattering. Elastic 125 1451 87 scattering serves as neutron cross section standard from 1 keV to 125 1451 88 20 MeV, with cross sections well determined. Uncertainties for 125 1451 89 elastic scattering rise from values well below 1%, reach maximum 125 1451 90 at about 8 MeV, then gradually decrease with increasing energy. 125 1451 91 In addition to elastic scattering, covariances are supplied for 125 1451 92 radiative capture. 125 1451 93 125 1451 94 REFERENCES 125 1451 95 [1] G.
