Measurement of near-threshold states in 12C using beta-delayed charged particle decay

ORAL

Abstract

The TexAT detector, an active target Time Projection Chamber (TPC), has recently been upgraded at the Cyclotron Institute at Texas A&M University. By utilizing the advantage of a TPC (4$\pi$ geometrical coverage), radioactive ion beams implanted into the chamber can be readily studied for rare processes. Of particular interest, to demonstrate the sensitivity of such a technique to probing 3-body correlations, is the decay mechanism of the $0_{2}^{+}$ state in $^{12}\mathrm{C}$, known as the Hoyle state. Using TexAT, this state is populated using $\beta^{+}$-decay of $^{12}\mathrm{N}$ and the $\beta$-delayed charged particles are measured and stopped inside the TPC. This talk will detail the latest results of this experiment and demonstrate the versatility of this technique.
