V000800200023 (E,30392002,L.Adamski+,W,MARCINKOWSKI,197703) V000800200024 ANALYSIS After performing re-normalization to each experimental V000800200025 results, the energy region has been divided into 3 V000800200026 and the polynomial fitting has been done to each V000800200027 region to supply 3 polynomials. And 4th polynomial V000800200028 was used to fit to all single energy data. V000800200029 (P(I),P(II),P(III)) V000800200030 then the 5th polynomial P(V) has been fitted to all V000800200031 4 polynomials, assuming a constant energy step. V000800200032 This procedure does not depend on the number of V000800200033 points in each excitation curve and gives an equal V000800200034 weight to the data sets. V000800200035 Csikai and Bayhurst's data have been separately fitted V000800200036 to the polynomials and normalized to P(V). V000800200037 finally those 2 polynomials and P(I),P(II) and P(III) V000800200038 were fitted to V000800200039 P(E)= sum((A(i)*(E**i)), i= 0 to 5. and V000800200040 A(0)= -3230.7, A(1)= 755.26, A(2)= -70.268, V000800200041 A(3)= 3.2762, A(4) = -.075663, A(5) = .00068650.
