On the scattering of fast neutrons by protons.
1. Introduction. Recent experiments by Amaldi arid his collaborators on the scattering of high-energy neutrons (of 10—15MeV.) by protons (2) have disclosed a considerable anisotropy in the angular distribution of the scattered particles. Theoretical discussions of this problem show an interesting feature in that the results depend sensitively on the basic assumptions involved with regard to the...
متن کاملQuasi-elastic Scattering of Neutrons
In solids random motions of atoms may take place in connection with disorder; for instance diffusion of interstitials in solid solutions or orientation fluctuations in molecular solids. Experimentally these motions are observed mostly by resonance and relaxation techni ques, by optical spectroscopy and, recently, by neutron spectroscopy. In comparison to the other me thods neutron spectroscop...
متن کاملTrabecular bone changes induced by fast neutrons versus gamma rays in mice
Background: The trabecular bone changes in the tibia of C3H/HeN mice were measured 12 weeks after whole body irradiation with various doses of fast neutrons (0-2.4 Gy) or 137Cs-generated gamma-rays (0-6 Gy). Materials and Methods: Serum calcium, phosphorus, estradiol concentration and alkaline phosphatase activity were measured. Tibiae were anal...

forenoon but failed on June 19. Weak transmission by scattered reflections also failed. Absorption of Ftransmission from WSXAL (6060 kc/s, 650 km distant) was greater than normal on June 19. The F2 virtual heights were very high when fz,* began to increase above fp, * from 1400 to 1600 EST June 19. This example of correlation of the condition of the ionosphere with a magnetic storm corroborates...
متن کاملMSGC test with fast neutrons
Results are presented from the exposure of a CMS performance prototype MSGC to a fast neutron beam having an average energy of 20 MeV and an intensity of 7 106 neutrons/mm2/s. A fluence equivalent to 3 years of LHC operation has been accumulated without damages to the detector. The stability of the MSGC operation in a heavily ionising particle flux is reported and the estimation of their produc...
