“…β-delayed 3αp decay has been observed for the first time. While β-delayed αp has been previously observed in 9 C [21], 17 Ne [22], 21 Mg [23] and 23 Si [24], these states did not provide any structural insight and instead were mainly seen through isobaric analogue states that were well fed by β-decay. In this work, β3αp decay was observed from the states below the isobaric analog in 13 N at E x = 15 MeV, demonstrating this is not merely a phasespace effect.…”

Background: The β-delayed proton-decay of 13 O has previously been studied, but the direct observation of β-delayed 3αp decay has not been reported.Purpose: Rare 3αp events from the decay of excited states in 13 N provide a sensitive probe of cluster configurations in 13 N.Method: To measure the low-energy products following β-delayed 3αp-decay, the TexAT Time Projection Chamber was employed using the one-at-a-time β-delayed charged-particle spectroscopy technique at the Cyclotron Institute, Texas A&M University.Results: A total of 1.9 × 10 5 13 O implantations were made inside the TexAT Time Projection Chamber. 149 3αp events were observed yielding a β-delayed 3αp branching ratio of 0.078(6)%. Conclusion:Four previously unknown α-decaying excited states were observed in 13 N at 11.3 MeV, 12.4 MeV, 13.1 MeV and 13.7 MeV and the decay modes for these states were established. We demonstrate that clustering must dominate the structure of these states to exhibit the observed decay branching ratios.
