A thick spherical target (R=25 cm) made of gabbro was irradiated isotropically with 1.6 GeV protons at the Saturne cyclotron at Laboratoire National Saturne (LNS)/CEN Saclay in order to simulate the interaction of galactic cosmic ray (GCR) protons wi

Considering the varied geophysical applications of 10Be, we have made an accurate measurement of the thermal neutron cross section for the reaction 10B(n, p)10Be. In the literature, only upper and lower limit values have been reported for this cross

The authors have measured the projectile and target $L$ x-ray spectra and cross sections for 41-MeV Ta projectiles bombarding thin targets between Ag and Th and for 17-60-MeV collisions of Ho on Ho, Au on Au, Pb on Pb, and U on Th. These cross sectio

The binary reaction products from the interaction of a 208Pb beam with targets of 26Mg, 27Al, 48Ca, 50Ti, 52Cr, 58Fe and 64Ni have been studied with the aid of a large position-sensitive ring counter, operated in a two-particle coincidence mode. The

Prompt K X-rays from evaporation residues formed in 350 MeV 84 Kr + K, Ni, Ge, Br and Y reactions have been observed. The X-ray yield is consistent with that expected from internal conversion in the gamma-cascade transitions of the evaporation residu

The anisotropy of the molecular orbital X-ray emitted in heavy-ion collisions was investigated for 18 systems with combined atomic numbers between 104 and 184. Well defined anisotropy peaks were observed which may reflect M-like transitions in the co

We have measured the spectra of continuum X-rays above the characteristic K lines for 4.5 to 4.8 MeV/N 20882Pb → 20882Pb, Pb → Bi, Bi → Pb and Bi → Bi collisions. Above ≈400 keV X-ray energy the spectral shape and intensity agree roughly wi

We propose a scheme of particle accelerators driven by far-infrared free-electron lasers on the basis of oversized periodically or helically corrugated hollow waveguides with cooled walls of high- T c superconductors. In this context, we discuss the
