The Doppler-shift attenuation method was applied to measure the lifetime of the 4.03 MeV state in Ne-19. By utilizing a He-3-implanted Au foil as a target, the state was populated using the Ne-20(He-3, alpha)Ne-19 reaction in inverse kinematics at a Ne-20 beam energy of 34 MeV. De-excitation gamma rays were detected in coincidence with alpha particles. At the 1 sigma level, the lifetime was determined to be 11(-3)(+4) fs and at the 95.45% confidence level the lifetime is 11(-7)(+8) fs.
