M026700100017 COMMENT The yield curve of the reaction M026700100018 Al-27(gamma,n)Al-26(m) has been determined by M026700100019 measuring the short-lived positron activity from the M026700100020 first excited state of 26Al. M026700100021 Analysis of the yield curve by the least structure M026700100022 method reveals a cross section consistent with, but M026700100023 with more detail than previous measurements, there M026700100024 being at least 14 resonances between threshold and M026700100025 23 MeV. Consistency is shown to exist between the M026700100026 energies of this peaks and the energies of those M026700100027 found in photoneutron and photoproton energy spectra M026700100028 from 27Al reported from other laboratories. M026700100029 The reaction threshold is found to be 13.27(0.05) M026700100030 MeV. M026700100031 The integrated cross section from threshold to 25 MeV M026700100032 is found to be 31(5) MeV*mb. M026700100033 Interpretation of the cross section is discussed. M026700100034 STATUS (CURVE) M026700100035 HISTORY (19880627C) M026700100036 (19910202A) Corrected by V.Varlamov, V.Mclane.
