Scanning tunneling spectroscopy of Bi2Sr2CaCu2O8þd reveals weak, incommensurate, spatial modulations in the tunneling conductance. When images of these energy-dependent modulations are Fourier analyzed the dispersion of their wave vectors can be determined. Comparison of the dispersions with angle-resolved photoemission indicates that quasiparticle interference, due to elastic scattering betwee...

Background. Thyroid cancer is the most common endocrine malignancy. The current standard of diagnosis, fine needle aspiration biopsy (FNAB) yields indeterminate results for approximately 10–25% of biopsies, necessitating thyroidectomy for diagnosis. Elastic scattering spectroscopy (ESS) is a minimally invasive optical biopsy technique that is sensitive to cellular and subcellular morphological ...

Two methods are discussed for the solar neutrino spectroscopy in the sub-MeV region: absorption in a loaded liquid scintillator and elastic scattering in a TPC. The different neutrino oscillation solutions predict a strong effect in this energy region where the largest fraction (∼98%) of solar neutrinos lies. Both projects have reached the stage where they have to prove their capability to atta...

Toward the end of his career, Zewail developed strong interest in fast electron spectroscopy and imaging, a field to which he made important contributions toward his aim of making molecular movies free of radiation damage. We therefore compare here the atomistic mechanisms leading to destruction of protein samples in diffract-and-destroy experiments for the cases of high-energy electron beam ir...

We report on low-temperature scanning tunneling spectroscopy measurements on epitaxial graphene flakes on Au(111). We show that using quasiparticle interference (QPI) mapping, we can discriminate between the electronic systems of graphene and Au(111). Beyond the scattering vectors, which can be ascribed to the elastic scattering within each of the systems, we observe QPI features related to the...

The elastic and inelastic profiles have been derived from the measured elastic differential cross section data with the help of exact impact parameter representation of elastic scattering amplitude. The results obtained for pp scattering at energy of 53 GeV and ¯ pp scattering at energy of 541 GeV have been presented. They indicate that nucleons can be regarded as objects characterized by a sma...

optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 gevic

Elastic scattering of energetic electrons over large angles (in this study 40 keV and 120◦) implies momentum and hence energy transfer from an lectron to a nucleus. Due to the large mass of the nucleus (relative to the mass of an electron) this energy transfer is small, but it has recently been hown that it can be resolved in a modern spectrometer. Hence the elastic peak of an overlayer/substra...

Optical spectroscopy show great promise for diagnosing the earliest stages of cancer. Light scattering spectroscopy (LSS), the study of single elastic backscattering as a function of wavelength and angle, can detect subcellular structural changes in early cancer. We have developed two novel differential light scattering spectroscopy techniques, space differential LSS (SD/LSS) and p-angle differ...
