M060500100014 SAMPLE Self-supporting (12.42 mg/cm**2) metal foil of M060500100015 natural tantalum (99.98 % 181Ta). M060500100016 DETECTOR (SILI) M060500100017 ANALYSIS (LEAST) The Cook least-square method for (g,p) M060500100018 reaction differential cross section obtaining from M060500100019 (e,e'p) reaction cross sections measured using the M060500100020 direct proton detection with the following M060500100021 integration over angles. M060500100022 COMMENT The energy distributions and the cross sections of M060500100023 the (e,e'p) reaction on 181Ta have been measured. M060500100024 The derived (g,p) cross section shows a strong M060500100025 resonance at around 21 MeV which is identified as M060500100026 the T> giant resonance. Two large proton groups M060500100027 were found in the proton spectra measured at E-e M060500100028 > 20.27 MeV. These proton groups and another M060500100029 small proton group are found to result from M060500100030 resonance at around 21 MeV. The proton groups are M060500100031 well described by the calculation of the T> giant M060500100032 resonance with the Nilsson model.
