Ultraviolet Photodissociation

The photodissociation dynamics of PCl3 at 235 nm has been studied by monitoring ground state Cl(2P3/2) and spin-orbitally excited Cl(2P1/2) atoms by resonance enhanced multiphoton ionization(REMPI). Also, the PCl+n (n=0,1,2)...

Abstract The velocity map imaging (VMI) technique was first introduced by Eppink and Parker in 1997, as an improvement to the original ion imaging method by Houston and Chandler in 1987. The method has gained huge popularity over the past two decades and has become a standard tool for measuring high-resolution translational energy and angular distributions of ions and electrons. VMI has evolved gradually from 2D momentum measurements to 3D measurements with various implementations and configurations. The most recent advancement has brought unprecedented 3D performance to the technique in terms of resolutions (both spatial and temporal), multi-hit capability as well as acquisition speed while maintaining many attractive attributes afforded by conventional VMI such as being simple, cost-effective, visually appealing and versatile. In this tutorial we will discuss many technical aspects of the recent advancement and its application in probing correlated chemical dynamics.

Traditionally, focused ion beam (FIB) microscopy systems have been used as instruments to repair integrated circuits, isolate defects or prepare mateiials for characterization with other techniques. Recently however, FIB microscopy has been used extensively as a standalone characterization technique. Typically, FIB microscopy can be used to probe site specific areas of a sample through secondary electron and ion imaging, energy dispersive x-ray analysis (EDX), or secondary ion mass spectroscopy (SIMS). These analyses will often combine two-dimensional elemental mapping or sputter depth profiles with imaging to investigate spatial variations of chemical and imaging signals. Inherently, these investigations are confined to two dimensions but often, complex materials problems are more easily understood if chemical and geometric information can be collected.

Resonance Relation

The paper presents a summary of the results obtained by C. J. Cohen and E. C. Hubbard, who established by numerical integration that a resonance relation exists between the orbits of Neptune and Pluto. The problem may be explored further by approximating the motion of Pluto by that of a particle with negligible mass in the three-dimensional (circular) restricted problem. The mass of Pluto and the eccentricity of Neptune's orbit are ignored in this approximation. Significant features of the problem appear to be the presence of two critical arguments and the possibility that the orbit may be related to a periodic orbit of the third kind.
