Creating High-Resolution Microscopic Cross-Section Images of Hardwood

Introduction. Transverse microscopic cross-sections of wood species have long been used for forensic wood identification, for analysis of critically important properties such as permeability and treatability with chemical agents, and to gain an understanding of the functioning of the tree (Zhang and Cai, 2006; Esteves and Pereira, ; Martins et al., ; Leggate et al., ; Lengowski et

5 Neutron reaction cross sections •Total microscopic neutron cross section is expressed as: σ= dN/dt / [(I/A) n A ∆x] • Defining neutron flux as: φ= I/A (neutrons/sec.cm2) • Then: dN/dt = φ(A ∆x n σ) • Neutron flux can also be defined: φ= nnvn where: nn is neutron density per cm3 in beam, vn relative velocity (cm/sec.) of neutrons in beam

Nuclear cross section - Wikipedia

Nuclear cross sections are used in determining the nuclear reaction rate, and are governed by the reaction rate equation for a particular set of particles (usually viewed as a "beam and target" thought experiment where one particle or nucleus is the "target" [typically at rest] and the other is treated as a "beam" [projectile with a given energy]). For neutron interactions incident upon a thin sheet of material (ideally made of a single type of is

Nuclear Cross Section - Macroscopic Cross Section

Macroscopic Cross Section. microscopic cross section for reaction, units: (usually barns or cm2). (per unit volume) in that material. The distinction between macroscopic and microscopic cross-section is that the former is a property of a specific lump of material (with its density), while the latter is an intrinsic property of a type of
