The deuteron beam was chopped and bunched to 3145300100011 produce 1 ns bursts at a frequency of 4 MHz. 3145300100012 SAMPLE Two cylindrical samples of natural iron, with dimen- 3145300100013 sions 3.0*2.8 cm and 2.0*2.8 cm. The first one was 3145300100014 used at 90 degree, the other at 55 and 125 degree 3145300100015 with respect tot the deuteron beam. 3145300100016 DETECTOR (NAICR) Two plastic-NaI anticoincidence shielded 3145300100017 spectrometers. 3145300100018 METHOD (TOF) The time-of-flight method was used to discrimi- 3145300100019 nate the neutrons and gamma-rays and to eliminate 3145300100020 events not associated with prompt gamma-rays. The 3145300100021 background spectrum was obtained from the NaI spec- 3145300100022 trum gated by a window equivalent in width to the 3145300100023 gamma-ray peak window, at constant background in the 3145300100024 TOF spectrum. 3145300100025 CORRECTION The gamma spectrum was corrected for background. 3145300100026 also corrections were made, by a Monte Carlo code, 3145300100027 for finite geometry, gamma-ray attenuation, neutron 3145300100028 attenuation and multiple scattering in the sample. 3145300100029 ERR-ANALYS (DATA-ERR) No error analysis given. 3145300100030 HISTORY (19951114C) HW.- 3145300100031 (20100219A) SD:Updated to new date formats,lower case. 3145300100032 STATUS (TABLE) Data are taken from author(priv. communication)3145300100033 ENDBIB 31 0 3145300100034 NOCOMMON 0 0 3145300100035 ENDSUBENT 34 0 3145300199999 SUBENT 31453002 20100307 31443145300200001 BIB 1 1 3145300200002 REACTION (26-FE-56(N,G)26-FE-57,,DA) 3145300200003 ENDBIB 1 0 3145300200004 COMMON 1 3 3145300200005 ANG 3145300200006 ADEG 3145300200007 90. 3145300200008 ENDCOMMON 3 0 3145300200009 DATA 3 5 3145300200010 EN DATA DATA-ERR 3145300200011 MEV MU-B/SR MU-B/SR 3145300200012 9.3 914. 137. 3145300200013 10.8 878. 132. 3145300200014 12.0 869. 130. 3145300200015 14.0 611. 91. 3145300200016 16.0 420. 63. 3145300200017 ENDDATA 7 0 3145300200018 ENDSUBENT 17 0 3145300299999 SUBENT 31453003 20100307 31443145300300001 BIB 1 1 3145300300002 REACTION (26-FE-56(N,G)26-FE-57,,DA) 3145300300003 ENDBIB 1 0 3145300300004 NOCOMMON 0 0 3145300300005 DATA 4 10 3145300300006 ANG EN DATA DATA-ERR 3145300300007 ADEG MEV MU-B/SR MU-B/SR 3145300300008 55. 9.0 717. 107. 3145300300009 55. 10.0 719. 108. 3145300300010 55. 12.5 654. 98. 3145300300011 55. 15.0 573. 86. 3145300300012 55. 20.0 264. 40. 3145300300013 125. 9.0 594. 89. 3145300300014 125. 10.0 594. 89. 3145300300015 125. 12.5 562. 84. 3145300300016 125. 15.0 441. 66. 3145300300017 125. 20.0 177. 27. 3145300300018 ENDDATA 12 0 3145300300019 ENDSUBENT 18 0 3145300399999 ENDENTRY 3 0 3145399999999
