Abstract：
Beta-delayed proton precursors ³³Ar and ⁴⁹Fe have been produced by the reaction ( ¹²C, 3n) using 65 MeV carbon ion bombardments of ²⁴Mg and ⁴⁰Ca respectively. Their beta-delayed proton spectra have been observed. The major proton peaks are at 3.28±0.07 MeV and 1.98±0.04 MeV for ³³Ar and ⁴⁹Fe respectively. While the corresponding cross-sections obtained for ³³Ar and ⁴⁹Fe are 0.4±0.08 μb and 0.7±0.14 μb respectively. The half-life of ³³Ar was determined to be 167+24 ms.
