Search for α-decay of ^229mTh produced from ²²⁹Ac β-decay following ²³²Th(γ, p2n) reaction

We produced ²²⁹Th in the nuclear reaction ²³²Th(γ,p2n) ²²⁹Ac, followed by disintegration to ^229m,gTh. The ^229mTh α-decay was searched for. Alpha-particle events of energy between 4.93 MeV and 5.05 MeV were observed in the separated thorium sample of β-decay products from an actinium source highly purified from the ²³²Th+γ reaction products. The energies of the α-particles coincide with those expected for ^229mTh.
