Abstract Soil moisture is a crucial variable in evaluating soil properties and its interaction with the atmosphere, yet none of techniques currently employed fully adequate for water content over an area hectares depth tens centimeters. In recent times, it has been shown how this volume can be accurately assessed measuring changes epithermal flux cosmic neutrons, which extremely sensitive to mo...

We are developing an experiment to measure the correlations a, A, and B, and the Fierz interference term b in neutron decay, with a precision of approximately 10(-4). The experiment uses an electromagnetic spectrometer in combination with two large-area segmented silicon detectors to detect the proton and electron from the decay in coincidence, with 4π acceptance for both particles. For the neu...
