13.5 MeV(d,p)(d,n) stripping to /sup 29/Si-/sup 29/P iso-states

The authors observed proton peaks corresponding to the g.s., 1.27, 2.03, 2.43, 3.07, 3.62, 4.08, 4.93, 5.65, 5.95 and (6.1+6.19) MeV-levels in /sup 29/Si, and neutron peaks corresponding to the g.s., 1.38, 1.96, 3.45, 4.34 and 4.76 MeV-levels in /sup 29/P. The protons and neutrons angular distributions were compared with D.W.B.A. calculations performed with the DWUCK code, in the Z.R.L. approximation. The deuteron optical parameters were extracted from an analysis of elastic scattering data.Anglai

Neutron-detector efficiency measurements from 7 to 14 MeV

The neutron efficiency of an Ne 102 plastic scintillator is measured for neutron energies from 7 to 14 MeV, using the D(d,n)/sup 3 /He reaction. The experimental results are compared with the prediction of two program codes. Different values of the /sup 12/C(n, alpha )/sup 9/Be reaction cross sections are introduced in the calculations; they strongly affect the calculated efficiency.Anglai

Fast neutron yields and spectra from targets of varying atomic number bombarded with deuterons from 16 to 50 MeV [for radiobiology and radiotherapy]

Neutron production from targets of Be, C, Mo, Cu, Ta and Au has been studied at the isochronous cyclotron at Louvain-la-Neuve. Neutron spectra were measured by the time of flight method. The yields of neutrons and gamma rays were also measured, and the greatest ratio of neutrons to gamma rays in the forward direction was found to occur with 50 MeV deuterons on a Be target. The angular distribution of neutrons from Be was measured at 16, 33 and 50 MeV, and neutron spectra were measured as a function of angle with 50 MeV deuterons on Be.Anglai

Neutron-proton capture at extreme angles at /b E//sub n/=61 MeV

The neutron-proton capture differential cross section at 0 degrees and 180 degrees center of mass angles was measured at a neutron energy of 61 MeV. A new setup was designed which improved the signal over background ratio. The 0 degrees cross section was found in agreement with the set of the other data around 60 MeV; the 180 degrees cross section is significantly lower than the 0 degrees cross section.Anglai
