The second M026400100019 was the 37 g sample in form of nitrogen gas, M026400100020 enriched to 98.9 % in N-15 contained in steel M026400100021 cylinder 2170 mm long and 42.4 mm outer diameter M026400100022 with walls 2.77 mm thick. M026400100023 ANALYSIS (PLA) The resulting yield curve for each target M026400100024 experiment was analysed using the variable bin M026400100025 Penfold-Leiss method (VBPL). For ammonium sulphate M026400100026 target because of presence of nuclei other than M026400100027 N-15, in order to deduce the yield curve of the M026400100028 desired reaction the additional yield curves both M026400100029 for sulphur and oxygen samples have been measured M026400100030 for target consisted of a suspension of 25.6 g of M026400100031 sulphur in 58.3 g of water contained in an identical M026400100032 lucite holder, and substracted. Allowance for the M026400100033 double counting of the N-15(g,2n) reaction was made M026400100034 by substracting the contribution of the N-15(g,2n) M026400100035 reaction, which was measured earlier. The total M026400100036 photoabsorption cross section was obtained using the M026400100037 (g,p) reaction data of Denisov. M026400100038 ERR-ANALYS (DATA-ERR) Mean root-square errors are given.

M026400100046 STATUS (TABLE) the data have been digitized in usa llnl and M026400100047 obtained by cdfe in the form of data tables. M026400100048 COMMENT Two independent measurements of the N-15(g,n)N-14 M026400100049 reaction cross section have been made using both an M026400100050 enriched-gas and ammonium sulphate powder targets. M026400100051 The results are self-consistent (only gas target M026400100052 data are presented), but reveal discrepancies with M026400100053 an earlier measurement of this cross section, M026400100054 particularly in the giant dipole resonance region, M026400100055 and with a measurement of N-15(g,n-0) cross section. M026400100056 These discrepancies are discussed and in general M026400100057 resolved. The results are used in conjunction with M026400100058 other isospin-selective reactions data on N-15 to M026400100059 elucidate the isospin distribution of e1 states in M026400100060 N-15.
