The decay property of 20Na was studied using a 20Mg beam to obtain a better understanding of the onset mechanism of the rapid proton process. The delayed protons were successfully measured, which correspond to one of the known 1+ states. There is no clear beta decay to the first excited 1+ state above the proton threshold in 20Na, suggesting that this state would not be the s-wave resonance as was expected before. The present result is preliminary; the final result will be published elsewhere.
