Determination of the Free Neutron Lifetime

We present the status of current US experimental efforts to measure the lifetime of the free neutron by the "beam" and "bottle" methods. BBN nucleosynthesis models require accurate measurements with 1 second uncertainties, which are currently feasible. For tests of physics beyond the standard model, future efforts will need to achieve uncertainties well below 1 second. We outline paths achieve both.

On the Search for Time Reversal Invariance Violation in Neutron Transmission

Time Reversal Invariant Violating (TRIV) effects in neutron transmission through a nuclei target are discussed. We demonstrate the existence of a class of experiments that are free from falls asymmetries. We discuss enhancement of TRIV effects. We analyze a model experiment and show that such tests have a discovery potential of $10^2 - 10^4$ compare to current limits.
