Intensity interferometry was applied to study electron correlations in doubly ionizing ion-atom collisions. In this method, the probability to find two electrons emitted in the same double ionization event with a certain momentum difference is compared to the corresponding probability for two uncorrelated electrons from two independent events. The ratio of both probabilities, the so-called correlation function, is found to sensitively reveal electron correlation effects, but it is rather insensitive to the collision dynamics. 相似文献

Entangled states whose Wigner functions are non-negative may be viewed as being accounted for by local hidden variables (LHV).
Recently, there were studies of Bell’s inequality violation (BIQV) for such states in conjunction with the well known theorem
of Bell that precludes BIQV for theories that have LHV underpinning. We extend these studies to teleportation which is also
based on entanglement. We investigate if, to what extent, and under what conditions may teleportation be accounted for via
LHV theory. Our study allows us to expose the role of various quantum requirements. These are, e.g., the uncertainty relation
among non-commuting operators, and the no-cloning theorem which forces the complete elimination of the teleported state at
its initial port. 相似文献

Isomeric states in 214Th and 213Th were identified by means of γ -rays measured in delayed coincidence with the implanted evaporation residues. These were
produced in irradiations of 164Dy with 54Cr projectiles and separated in-flight by the velocity filter SHIP. An isomeric state of I
π = 8+ with a half-life of (1.24±0.12) μs was identified in 214Th . The configuration π[1h
9/2 ⊗ 2f
7/2] was assigned to this state. An isomeric state with a half-life of (1.4±0.4) μs was observed in 213Th . Tentatively it was assigned to an I
π = 13/2+ state. 相似文献
