Photon angular distribution in nuclear excitation by electron capture

In the resonant process of nuclear excitation by electron capture (NEEC), a free electron is captured into a bound atomic shell with the simultaneous excitation of the nucleus. NEEC is a process analogous to dielectronic recombination (DR), and when followed by the radiative decay of the nucleus, it is a competing resonant channel of radiative recombination (RR). Partly due to the dominant RR b...

Two-photon excitation STED microscopy.

We report sub-diffraction resolution in two-photon excitation (TPE) fluorescence microscopy achieved by merging this technique with stimulated-emission depletion (STED). We demonstrate an easy-to-implement and promising laser combination based on a short-pulse laser source for two-photon excitation and a continuous-wave (CW) laser source for resolution enhancement. Images of fluorescent nanopar...

Two-photon excitation fluorescence microscopy.

Two-photon fluorescence microscopy is one of the most important recent inventions in biological imaging. This technology enables noninvasive study of biological specimens in three dimensions with submicrometer resolution. Two-photon excitation of fluorophores results from the simultaneous absorption of two photons. This excitation process has a number of unique advantages, such as reduced speci...

Isomer triggering via nuclear excitation by electron capture.

Triggering of long-lived nuclear isomeric states via coupling to the atomic shells in the process of nuclear excitation by electron capture (NEEC) is studied. NEEC occurring in highly charged ions can excite the isomeric state to a triggering level that subsequently decays to the ground state. We present total cross sections for NEEC isomer triggering considering experimentally confirmed low-ly...

Enhanced two-photon fluorescence excitation by resonant grating waveguide structures.

Enhanced two-photon fluorescence (TPF) spectroscopy with novel high-finesse resonant polymeric grating waveguide structures (GWSs) is presented. Under resonant conditions the field enhancement at the surface of a GWS can be exploited for TPF spectroscopy without the need for highly focused laser excitation light. We compare the TPF obtained by placing a drop of tetramethylrhodamine (TMR) on top...
