Electron-correlation driven capture and release in double quantum dots.
We recently predicted that the interatomic Coulombic electron capture (ICEC) process, a long-range electron correlation driven capture process, is achievable in gated double quantum dots (DQDs). In ICEC an incoming electron is captured by one quantum dot (QD) and the excess energy is used to remove an electron from the neighboring QD. In this work we present systematic full three-dimensional el...
متن کاملCorrelated double-electron capture with emission of a single photon
Double photoionization of an atom caused by the absorption of a single photon, the so-called double photoeffect, is a fundamental phenomenon, in which correlation effects play a crucial role. Since the photon interacts only with a single electron, the simultaneous ejection of two electrons is exclusively caused by the electron-electron interaction. So far experiments have been performed with he...
متن کاملYoung–type interferences in the two–photon decay of heavy helium–like ions∗
The characteristic photon emission from highly– charged, heavy ions has been in the focus of experimental studies at the GSI facility for many years [1]. Apart from the one–photon bound–bound transitions, the two–photon decay of metastable ionic states has attracted much interest since it may reveal unique knowledge on the complete spectrum of high–Z ions, including the negative continuum of Di...
متن کاملDouble-to-single target ionization ratio for electron capture in fast p-He collisions.
We have used the ion storage ring CRYRING and its internal gas-jet target and recoil-ion-momentum spectrometer to measure absolute cross sections for transfer ionization (TI: p+He-->H0+He2++e(-)) in 2.5-4.5 MeV p-He collisions with separate Thomas (TTI) and kinematic (KTI) TI contributions. The probability for electron emission in kinematical capture decreases with increasing velocity and appea...
متن کاملNuclear-atomic state degeneracy in neutrinoless double-electron capture: A unique test for a Majorana-neutrino
There is a general consensus that detection of a double-beta decay without any neutrino involved would mark physics beyond the Standard Model. This is because in such decay modes lepton number conservation would be violated and the neutrino would reveal itself as being its own antiparticle. It is this particle-antiparticle duality which makes the neutrino of Majorana type. So far, the experimen...
