1.1 This test method covers procedures for measuring reaction rates by the activation reactions 46 Ti (n, p) 46 Sc + 47 Ti (n, np) 46 Sc.
Note 1-Since the cross section for the (n,np) reaction is relatively small for energies less than 12 MeV and is not easily distinguished from that of the (n,p) reaction, this test method will refer to the (n,p) reaction only.1.2 The reaction is useful for measuring neutrons with energies above approximately 4.4 MeV and for irradiation times up to about 250 days (for longer irradiations, see Note 2).
1.3 With suitable techniques, fission-neutron fluence rates above 10 cm -2 [dot]s -1 can be determined. However, in the presence of a high thermal-neutron fluence rate, 46 Sc depletion should be investigated.
1.4 Detailed procedures for other fast-neutron detectors are referenced in Test Method E261.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
