Recoil scattering

B1.24 Rutherford backscattering, resonance scattering, PIXE and forward (recoil) scattering... [Pg.1827]

This overview covers the major teclnhques used in materials analysis with MeV ion beams Rutherford backscattering, chaimelling, resonance scattering, forward recoil scattering, PIXE and microbeams. We have not covered nuclear reaction analysis (NRA), because it applies to special incident-ion-target-atom combinations and is a topic of its own [1, 2]. [Pg.1829]

Also known as forward recoil scattering (FRS) or hydrogen forward scattering (HFS). [Pg.429]

Elastic Recoil Detection (ERD) also referred to as Elastic Recoil Detection Analysis (ERDA), Elastic Recoil Scattering (ERS), Eorward Recoil Scattering (FRS), Forward Recoil Spectrometry (FReS), and Hydrogen Forward Scattering (HFS)... [Pg.267]

There are two basic physical phenomena which govern atomic collisions in the keV range. First, repulsive interatomic interactions, described by the laws of classical mechanics, control the scattering and recoiling trajectories. Second, electronic transition probabilities, described by the laws of quantum mechanics, control the ion-surface charge exchange process. [Pg.1801]

The energy of scattered or recoiled ions can be measured directly by means of an electrostatic energy analyser. If the TOF method is used, the relation between scattering energy E and TOF is expressed as... [Pg.1802]

In TOF-SARS [9], a low-keV, monoenergetic, mass-selected, pulsed noble gas ion beam is focused onto a sample surface. The velocity distributions of scattered and recoiled particles are measured by standard TOF methods. A chaimel electron multiplier is used to detect fast (>800 eV) neutrals and ions. This type of detector has a small acceptance solid angle. A fixed angle is used between the pulsed ion beam and detector directions with respect to the sample as shown in figure Bl.23.4. The sample has to be rotated to measure ion scattering... [Pg.1805]

A = /W//Wp, P is impact parameter and Tq is the distance of closest approach (apsis) of the collision pair. The transformations from the CM coordinates (scattering angle y) to the laboratory coordinates with the scattering angle 0 for the primary particle and (]) for the recoiled surface atoms Is given by... [Pg.1809]

For accurate ion trajectory calculation in the solid, it is necessary to evaluate the exact positions of the intersections of the asymptotes (A A2) of the incoming trajectory and that of the outgoing trajectories of both the scattered and recoiled particles in a collision. The evaluation of these values requires time integrals and the following transfonnation equations ... [Pg.1810]

TOF-SARS and SARIS are capable of detecting all elements by either scattering, recoiling or both teclmiques. TOF peak identification is straightforward by converting equation (Bl.23.lt and equation (B 1.23.81 to the flight times of the scattered and recoiled particles as... [Pg.1812]
