Title: Study of the possibility of solving cosmological lithium problem in an accelerator experiment

Abstract

Within the standar dmodel of Big Bang Nucleosynthesis (BBN), there is a cosmological lithium problem, which consists in a substantial difference between calculated data on the abundances of the isotopes {sup 6}Li and {sup 7}Li and those that were found from observational astronomy. An attempt at measuring the cross section for the main 6Li production reaction {sup 2}H({sup 4}He, γ){sup 6}Li induced by the interaction of {sup 4}He{sup +} ions with deuterons at collision energies less than the lower boundary of the BBN energy range was made in the present study. Upper limits on the cross sections for the reaction in question were set.

  • The possibility was shown, by an analysis of the quantum theory of measurement, of solving experimentally the problem of the complete'' character of quantum mechanics. The same procedure permits an experimental verification of the theory of the double solution. It is also evident that there is independence between the uncertainty principle and the indeterministic character of the quantum formulism. (tr-auth)
  • We apply a recent proposal for defining states and observables in quantum gravity to some simple models. First, we consider the toy model of a Klein-Gordon particle in an external potential in Minkowski spacetime and compare our proposal to the theory obtained by deparametrizing with respect to a choice of time slicing prior to quantization. We show explicitly that the dynamics defined by the deparametrization approach depends upon the choice of time slicing. On the other hand, our proposal automatically yields a well defined dynamics, manifestly independent of the choice of time slicing at intermediate times, but there is amore » memory effect'': After the potential is turned off, the dynamics no longer returns to the standard, free particle dynamics. Next, we apply our proposal to the closed Robertson-Walker quantum cosmology with a homogeneous massless scalar field. We choose our time variable to the size of the Universe, so the only dynamical variable is the scalar field. It is shown that the resulting theory has the expected semiclassical behavior up to the classical turning point from expansion to contraction; i.e., given a classical solution which expands for much longer than the Planck time, there is a quantum state whose dynamical evolution closely approximates this classical solution during the expanding phase. However, when the time'' takes a value larger than the classical maximum, the scalar field becomes frozen'' at the value it had when it entered the classically forbidden region. The Taub model, with and without a homogeneous scalar field, also is studied, and similar behavior is found. In an Appendix, we derive the form of the Wheeler-DeWitt equation on minisuperspace for the Bianchi models by performing a proper quantum reduction of the momentum constraints; this equation differs from the usual form of the Wheeler-DeWitt equation, which is obtained by solving the momentum constraints classically, prior to quantization.« less
  • We analyze cosmological solutions in the class of two-brane models with arbitrary tensions which contain matter with general equations of state. We show that the mass hierarchy between the two branes is determined by the ratio of the lapse functions evaluated on the branes. This ratio can be sufficiently small without fine-tuning the brane separation, once the transverse dimension is stabilized. For suitably large interbrane separations, both brane tensions are positive. We also find that the cosmological evolution obeys the standard four-dimensional Friedmann equation up to small corrections.
  • We describe a modification to a transmission electron microscope (TEM) that allows it to briefly (using a pulsed-laser-driven photocathode) operate at currents in excess of 10 mA while keeping the effects of condenser lens aberrations to a minimum. This modification allows real-space imaging of material microstructure with a resolution of order 10 nm over regions several {micro}m across with an exposure time of 15 ns. This is more than 6 orders of magnitude faster than typical video-rate TEM imaging. The key is the addition of a weak magnetic lens to couple the large-diameter high-current beam exiting the accelerator into themore » acceptance aperture of a conventional TEM condenser lens system. We show that the performance of the system is essentially consistent with models derived from ray tracing and finite element simulations. The instrument can also be operated as a conventional TEM by using the electron gun in a thermionic mode. The modification enables very high electron current densities in {micro}m-sized areas and could also be used in a non-pulsed system for high-throughput imaging and analytical TEM.« less
