The problem of radiation heat transfer in a semitransparent infinite plane parallel layer with purely diffusive reflection, emission and transmission behaviour (referred to as optical boundary conditions), in which the temperature depends only on the

The transient thermal behavior of 200 and 300 mm wafers in a new rapid thermal processing (RTP) chamber is investigated. The AST3000 is a new RTP tool to meet the process requirements for both wafer sizes in 0.18 µm technologies and beyond. In this

The ratio R = σ L σ T of longitudinal and transverse cross sections for the reaction ep → ep η at the resonance S 11 (1535) was measured at momentum transfers q 2 = 0.6 and 1 GeV 2 . The transverse part dominates the longitudinal part of the cro

All existing data on γ v p total cross sections in the resonance region are fitted in the absolute value of the three-momentum transfers | q | independently for small bins of W in the range 1.11 ⩽ W ⩽ 1.99 GeV. The data are divided into three ra

Recent measurements on electroproduction of π0 mesons in the region of the first pion nucleon resonance at four momentum transfers of q2 = 0.6 and q2 = 1 GeV are extended to q2 = 1.56 GeV2. All the results are discussed in terms of angular coefficie
