A pulsed core-sampling photofragment translational spectroscopy (PTS) method with a long time-delay, which allows an extremely high kinetic energy resolution, is presented in this article. More commonly applying a short time delay between laser and pulsed acceleration electric field leads to a low kinetic energy resolution for the pulsed core-sampling method. This low kinetic energy resolution problem was overcome by applying a longer time delay. An absolute recoil velocity resolution of Δv=8 m/s and a relative kinetic energy resolution of ΔE/E=3.6% were obtained in this experiment, by applying a time-delay of 8 μs between the laser and the acceleration electric field. The vibrational distributions of the CH3 radical for the I* and I channel of CH3I photodissociation at 266 nm were directly resolved for first time to presented an improvement of the kinetic energy resolution.
