Single-Particle Strengths for Quasibound Levels inCl33

Wave function microscopy of quasibound atomic states.

In the 1980s Demkov, Kondratovich, and Ostrovsky and Kondratovich and Ostrovsky proposed an experiment based on the projection of slow electrons emitted by a photoionized atom onto a position-sensitive detector. In the case of resonant excitation, they predicted that the spatial electron distribution on the detector should represent nothing else but a magnified image of the projection of a quas...

Effects of interplanetary transport on derived energetic particle source strengths

[1] We study the transport of solar energetic particles (SEPs) in the inner heliosphere in order to relate observations made by an observer at 1 AU to the number and total energy content of accelerated particles at the source, assumed to be near the Sun. We use a numerical simulation that integrates the trajectories of a large number of individual particles moving in the interplanetary magnetic...

Automatic Particle Picking Algorithms for High Resolution Single Particle Analysis

As new genome sequencing initiatives are completed, one of the next great challenges of cell biology is the atomic resolution structure determination of the enormous number of proteins they encode. Single particle analysis is a technique which produces 3D structures by computationally aligning high resolution electron microscope images of individual, randomly oriented molecules. One of the limi...

Particle segmentation algorithm for flexible single particle reconstruction

As single particle cryo-electron microscopy has evolved to a new era of atomic resolution, sample heterogeneity still imposes a major limit to the resolution of many macromolecular complexes, especially those with continuous conformational flexibility. Here, we describe a particle segmentation algorithm towards solving structures of molecules composed of several parts that are relatively flexib...
