Tailoring Laser-Generated Plasmas for Efficient Nuclear Excitation by Electron Capture

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...

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...
