corrected 3040900100023 ERR-ANALYS (DATA-ERR) Errors are mainly due to the uncertainty in 3040900100024 fitting the analytic spectra to the experimental data. 3040900100025 (ERR-1) A further error, of approximately 5%, can be 3040900100026 attributed to the uncertainties in the stripping 3040900100027 process, the deuteron 'bump' integral and (n,d) cross- 3040900100028 section. 3040900100029 ENDBIB
