First Observation of the β3αp Decay of ¹³O via β-Delayed Charged-Particle Spectroscopy

RADIOACTIVITY ¹³O(β⁺p3α) [from ³He(¹⁴N, ¹³O), E=15.1 MeV/nucleon]; measured decay products, Eα, Iα. ¹³N; deduced β-delayed 3αp branching ratio, four previously unknown α-decaying excited states in ¹³N. Comparison with systematics. The K500 Cyclotron at Texas AM University, the Texas Active Target (TexAT) time projection chamber.
