Abstract：
The enriched neon was bombarded by 35.5MeV protons from linear accelerator at Institute of High Energy Physics.The spctra of beta delayed alpha decay of ²⁰Na were obtained.A new peak at 0.78MeV was observed in the spectra.From the particle identification,particle spectra and the life time measurement it was believed that the peak at 0.78MeV was from low energy alpha decay channel first observed in the beta delayed alpha decay of ²⁰Na.
