Abstract

The β-delayed triple-α particle decay of ¹²B has been measured with a setup that favours coincidence detection. A broad state in ¹²C, previously reported around 10 MeV, has been seen and its properties determined through R-matrix analysis of the excitation spectrum. The spin and parity are 0⁺. Interference between this state and the Hoyle state at 7.654 MeV has a marked influence on the spectrum. The coupling between the two states makes it difficult to determine the resonance energy. © 2005 Elsevier B.V. All rights reserved.
