“…1 that the cross sections from the present experiment fall along high side of the upper curve previously set by the measurements of Anders et al [6] and Welch et al [7] and calculations of Dimbylow [5]. The predictions of Dimbylow [5] are within our error bars, as are, for the most part, the measurements from Anders et al [6] and Welch et al [7]. …”

The solid red symbols are from this experiment using the polyethylene target and both NaI detectors in coincidence; the larger of the associated error bars indicates the increase in overall uncertainty when the uncertainty in incident neutron energy is included.…”

C12(n, 2n)C11 cross section from threshold to 26.5 M

The 12C(n, 2n)11C cross section was measured from just below threshold to 26.5 MeV using the Pelletron accelerator at Ohio University. Monoenergetic neutrons, produced via the 3H(d,n)4He reaction, were allowed to strike targets of polyethylene and graphite. Activation of both targets was measured by counting positron annihilations resulting from the β+ decay of 11C. Annihilation gamma rays were detected, both in coincidence and singly, using back-to-back NaI detectors. The incident neutron flux was determined indirectly via 1H(n,p) protons elastically scattered from the polyethylene target. Previous measurements fall into upper and lower bands; the results of the present measurement are consistent with the upper band.

“…For example, the excitation function for the 12 C(n,2n) n C reaction in SCINFUL is shown in Figure 7. It agrees with the recent data of Anders et al 30 up to 34 MeV, cross section data being somewhat larger than earlier data. 31 For E n > 34 MeV one can only "evaluate" the excitation function by a "best estimate" smooth curve which intersects 22 mb at E" = 90 MeV, i.e., the value quoted (but not measured) by Kellogg.…”

A systematic study on neutron activation cross-section measurements in the energy from 20 MeV to 150 MeV has been performed over several years. For this study, we have developed the quasi-monoenergetic neutron fields using 7U(p,n) reaction at three AVF cyclotron facilities; 1) Institute for Nuclear Study, University of Tokyo for 20 to 40 MeV protons, 2) Takasaki Institute of Advanced Radiation Applications(TIARA) of Japan Atomic Energy Research Institute(JAERI) for 40 to 90 MeV protons, 3) Institute of Physical and Chemical Research(RIKEN) for 70 to 210 MeV protons. By using these neutron fields, we have measured the activation cross sections of 30Si(n,np), 47Ti(n,np), 48TI(n,np), 52Cr(n,2n), 58Ni(n,2n) in the energy range of 15 to 40 MeV, and of 12qn,2n), 59Co(n,xn) and (n,xnp), natCu(n,xn) and (n,xnp), 209Bi(n,xn) in the energy range of 15 to 80 or 150 MeV. We are now developing a new p-Li quasi-monoenergetic neutron field in the energy range of 20 to 90 MeV using a new AVF cyclotron installed in the Cyclotron and Radioisotope Center, Tohoku University, for measurements of neutron activation cross sections of light elements such as 0 and N which are included in air, water and soil.
