Abstract

A study of the ⁷Li(⁹Be, ⁴He ¹⁰Be)²H reaction at E_beam = 70 MeV has been performed using resonant particle spectroscopy techniques and provides the first measurements of α-decaying states in ¹⁴C. Excited states are observed at 14.7, 15.5, 16.4, 18.5, 19.8, 20.6, 21.4, 22.4, and 24.0 MeV. The experimental technique was able to resolve decays to the various particle bound states in ¹⁰Be and provides evidence for the preferential decay of the high energy excited states into states in ¹⁰Be at ∼6 MeV. The decay processes are used to indicate the possible cluster structure of the ¹⁴C excited states.
