Abstract：
The β-delayed α decay of ²⁰Na was restudied using neon target bombarded by 25 and 35.5 MeV protons.In this experiment a newly developed particle-telescope system including a gas ionization chamber as a thin ΔE detector was used. Two new peaks,one at 0.695 MeV and other at 0.907 MeV, were observed for the first time in the charged particle spectra. Based on particle identification, branching ratio and life time measurement,it is believed that these new peaks result from β-delayed low energy αdecay of ²⁰Na.The decay scheme and the low-lying level scheme of 20Na were thus revised.Its possible astrophysical implications were discussed.
