When a laser pulse of intensity 10(19) W cm(-2) interacts with solid targets, electrons energies some tens MeV are produced. In tantalum target, the generate an intense highly directional gamma-ray beam that can be used to carry out photonuclear reactions. The isotopes 11C, 38K, (62,64)Cu, 63Zn, 106Ag, 140Pr, and 180Ta have been produced by (gamma,n) reactions using VULCAN beam. addition, laser-induced nuclear fission in 238U has demonstrated, process which was theoretically predicted at...
Novel measurements of electromagnetic radiation above 10 MeV are presented for ultra intense laser pulse interactions with solids. A bright, highly directional source γ rays was observed directly behind the target. The were produced by bremsstrahlung from energetic electrons generated during interaction. They measured using photoneutron reaction [63Cu(γ,n)62Cu] in copper. resulting activity coincidence counting positron annihilation which decay Cu62. New at 1019 W cm−2 also presented.
Direct links between carbonaceous chondrites and their parent bodies in the solar system are rare. The Winchcombe meteorite is most accurately recorded chondrite fall. Its pre-atmospheric orbit cosmic-ray exposure age confirm that it arrived on Earth shortly after ejection from a primitive asteroid. Recovered only hours falling, composition of largely unmodified by terrestrial environment. It contains abundant hydrated silicates formed during fluid-rock reactions, carbon- nitrogen-bearing...
Abstract The history of agricultural terraces remains poorly understood due to problems in dating their construction and use. This has hampered broader research on significance, limiting knowledge past practices the long-term investment choices rural communities. authors apply OSL profiling sediments associated with across Mediterranean region date Results from five widely dispersed case studies reveal that although many were used first millennium AD, most intensive episodes terrace-building...
We integrated optically stimulated luminescence dating and 10 Be cosmogenic nuclide measurements to quantify short‐to‐medium‐term (10 2 –10 4 years) catchment dynamics response active tectonics. In the 27 km Río Torrente catchment, Sierra Nevada, southern Spain, rapid base‐level fall has triggered knickpoint migration up both trunk tributary channels, resulting in two distinct geomorphic zones: (1) a steep lower with concordant rates of hillslope erosion channel incision over short (100...
Abstract Optically stimulated luminescence (OSL) is a technique that has been applied from the mid‐1980s, mainly for sediment dating. The OSL based on sample stimulation by light to determine signal stored in crystal lattices of grains after deposition, burial later and subsequent exposure ionizing radiation radioactive elements surrounding sediment. In such dating, two parameters are required: equivalent dose (i.e. grains), rate energy α, β γ emitted naturally occurring radioisotopes...
We have studied laminated sediments from Lake Esmeralda, Vega Island, in order to reconstruct its history. describe both inorganic and organic components of the sediment using a combination following analytical methods: x-ray fluorescence (XRF), diffraction (XRD), magnetic susceptibility measurement, chemical analysis for determination cation exchange capacity, grain size determination, geochemical analyses (total carbon (TIC), total (TOC), sulphur (TS)), spectrophotometry, high-pressure...
Optically stimulated luminescence (OSL) dating of sand has been used to identify periods enhanced aeolian activity at two coastal archaeological sites in Orkney that coincide with Holocene climatic deterioration recorded elsewhere both Scotland and W Europe. Areas Tofts Ness, Sanday were settled from the Neolithic, abandoned late Neolithic/early Bronze Age, reoccupied permanently Iron Age. Sand layers above Neolithic soils have OSL dated about 4000 BP, correlating well a period increased...
