In 2367500200021 this detection system, the recoil proton telescope 2367500200022 was at a proton emission angle theta,p of 25 deg. 2367500200023 In this case, the measured fission cross section is 2367500200024 proportional to the differential proton emission 2367500200025 cross section dsigma/dOmega,p at theta,p) in the 2367500200026 laboratory frame. 2367500200027 Therefore, it is possible to re-normalized it in 2367500200028 case of change of the neutron-proton elastic 2367500200029 scattering cross section at the corresponding neutron 2367500200030 scattering angle. 2367500200031 2.PPAC+MSRPT dataset 2367500200032 The cross section obtained with PPAC and MS-RPTL and 2367500200033 MS-RPTH. In this detection system two recoil proton 2367500200034 telescopes were used, positioned at 25 deg and 20 deg,2367500200035 respectively. 2367500200036 In this case the normalization is not straightforward, 2367500200037 therefore we are proposing a method (outlined in ????)2367500200038 for the re-normalization. 2367500200039 MISC-COL 2(MISC) [w(20 deg)*phi(20 deg)]/[w(25 deg)*phi(25 deg)] 2367500200040 ERR-ANALYS (ERR-T) Total uncertainty 2367500200041 (ERR-S) Statistical uncertainty 2367500200042 (ERR-SYS) Total systematic uncertainty 2367500200043 (ERR-2) Systematic uncertainty correlated between PPFC 2367500200044 and PPAC datasets: 2367500200045 .

2367500300011 of the two independent results (in which we have a 2367500300012 contribution from both the neutron-proton elastic 2367500300013 scattering differential cross section). 2367500300014 This data set contains the weights used to calculate 2367500300015 the weighted mean, which makes it possible to 2367500300016 re-calculate the weighted mean of the re-normalized 2367500300017 fission cross sections measured with the two 2367500300018 experimental configurations PPFC/3S-RPT and 2367500300019 PPAC/MS-RPTL(H). 2367500300020 As discussed in E.Pirovano et al. "Absolute cross 2367500300021 section for neutron-induced fission of 235U in the 2367500300022 energy range from 10 MeV to 400 MeV" (to be published 2367500300023 in Phys.Rev.C and arXiv), these two data sets are 2367500300024 partially correlated, as the same polyethylene 2367500300025 samples and beam intensity monitors were employed. 2367500300026 However, a small re-normalization of the differential 2367500300027 neutron-proton scattering cross section will not 2367500300028 effect the stated relative uncertainty of the final 2367500300029 fission cross section. 2367500300030 STATUS
