The Ultracold Neutron Asymmetry (UCNA) experiment was designed to measure the-decay asymmetry parameter,, for free neutron decay. In the experiment, polarized ultracold neutrons are transported into a decay trap, and their-decay electrons are detected withacceptance into two detector packages which provide position and energy reconstruction. The experiment also has sensitivity to, the Fierz interference term in the neutron-decay rate. In this work, we determinefrom the energy dependence ofusing the data taken during the UCNA 2011–2013 run. In addition, we present the same type of analysis using the earlier 2010dataset. Motivated by improved statistics and comparable systematic errors compared to the 2010 data-taking run, we present a newmeasurement using the weighted average of our asymmetry dataset fits, to obtainwhich corresponds to a limit ofat the 90% confidence level.
