D: <strong>File</strong>s are duplicates of IRDF-90 files.<br />
N: No cross-section data were available; plots were not prepared.<br />
Q: New evaluation is nearly complete, but not yet available for consideration.<br />
a<br />
<strong>File</strong>s did not meet the requirements specified for the covariance matrices, but were<br />
included due to their importance for reactor dosimetry.<br />
— 46 Ti(n,2n) 45 Ti: Experimental data were evaluated and renormalized by<br />
Zolotarev. Both the JENDL and RRDF evaluations are very similar and<br />
fit the data reasonably well, although the RRDF gives the best fit.<br />
— 46 Ti(n,p) 46 Sc: Evaluations were available in the IRDF, JENDL and<br />
RRDF, and all of them appear to be lower than the average of the experimental<br />
data. JENDL gives the best fit for all the data, although the IRDF<br />
and RRDF fit some of the data with the lowest uncertainties. Evaluator<br />
comments are very helpful and should be studied.<br />
—Ti(n,x) 46 Sc: JENDL is the only file available, and the evaluated crosssection<br />
is slightly higher than the available data from natural titanium.<br />
— 47 Ti(n,np+pn+d) 46 Sc: Experimental data were evaluated and renormalized<br />
by Zolotarev. Limited data include measurements of (n,np+d).<br />
The IRDF and RRDF are distinctly different, and the RRDF clearly<br />
gives the best fit to the data.<br />
— 47 Ti(n,p) 47 Sc: Experimental data were evaluated and renormalized by<br />
Zolotarev. The IRDF is the only available cross-section file. The<br />
evaluation appears to be somewhat lower than the available experimental<br />
data, although they exhibit considerable scatter.<br />
— 48 Ti(n,np+pn+d) 47 Sc: Experimental data were evaluated and renormalized<br />
by Zolotarev. Limited data include measurements of (n,np+d).<br />
Evaluations are available from the IRDF, RRDF and JENDL that all fit<br />
the data equally well.<br />
