Recent Results with Texas Active Target (TexAT) Detector System

PHY Seminar

Abstract: TexAT is an Active Target Detector System designed for a wide range of experiments with radioactive beams. These experiments target the structure of exotic nuclei, clustering phenomena in nuclei, nuclear astrophysics, and searches for exotic decay modes. 

I will discuss several recent results obtained with TexAT and highlight the active target approach’s advantages, limitations, and future perspectives. I will focus on the following topics: a) rare decay modes were observed in β-delayed charged particle spectroscopy of 12N and 13O experiments performed with TexAT at Texas A&M University. In particular, democratic” triple-alpha emission from the Hoyle state in 12C and the exotic β3αp decays in 13O will be discussed; b) cluster states in 18Ne were studied using α+14O resonance elastic scattering leading to hints for super-radiance phenomena when compared to the mirror α+14C system.
