Description
The Doppler-shift attenuation method was applied to measure the lifetime of the 4.03 MeV state in 19Ne. By utilizing a 3He-implanted Au foil as a target, the state was populated using the 20Ne(3He, α)19Ne reaction in inverse kinematics at a 20Ne beam energy of 34 MeV. De-excitation γ rays were detected in coincidence with α particles. At the 1σ 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
