{"product_id":"novel-gamma-ray-and-thermal-neutron-scintillators","title":"Novel Gamma-Ray and Thermal-Neutron Scintillators","description":"In this book, bromide and iodide scintillators, which have been investigated for the past four years, are presented. Three major groups of compounds were studied; lanthanide trihalides LnX3, (pseudo)-elpasolites M2ALnX6 and ternary halides AmLnnXo. Where M and A are alkali cations, Ln is a rare earth cation and X is a halide anion. Some materials show interesting [gamma]-scintillation properties. LuI3: Ce3+, one of lanthanide trihalides, has a record high light output of 98,000 photons\/MeV and a fast response of 35 ns. Two other groups, (pseudo)-elpasolites and ternary halides, show relatively low light yields.For thermal neutron scintillator, the focus was on (pseudo)-elpasolites M2LiLnX6 and ternary halides LimLnnXo groups. Rb2LiYBr6: Ce3+ shows an excellent neutron peak resolution of 3.6 per cent. This is the best neutron peak resolution ever reported. Together with the large [alpha]\/[beta] ratio of 0.74, Rb2LiYBr6: Ce3+ offers the possibility of excellent neutron\/[gamma] discrimination. The highest thermal neutron scintillation light yield of 83,000 photons\/neutron is also reported for Rb2LiYBr6: Ce3+. The analysis for all halide scintillators is also presented.\nLimitation in their light yields and response times is discussed.","brand":"IOS Press","offers":[{"title":"Default Title","offer_id":54877260906840,"sku":"9781586038168","price":50.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9781586038168.jpg?v=1777950045","url":"https:\/\/agendabookshop.com\/products\/novel-gamma-ray-and-thermal-neutron-scintillators","provider":"Agenda Bookshop","version":"1.0","type":"link"}
