The virtual-state character of the {9}^Be 1/2^+ state in the {9}^Be(γ,n){8}^Be reaction

Myagmarjav Odsuren, Yuma Kikuchi, Takayuki Myo +2

We study the character of the first excited 1/2^{+} state of {9}^Be, which is observed as a low-lying sharp peak in the cross section of 9^Be(γ,n)2α just above the {8}^Be+n thresho…
