It is found here that the 1/2 + first excited state of 9 Be is a virtual state with the energy of-23.5 KeV. The line shape for the excitation of the state is approximated with a simple analytic form based on the effective range expansion. The partner in 9 B of this state is found to be a resonance with a maximum in the peak at about 1.1 MeV, FWHM of 1.5 MeV, and complex energy of 0.6 − i0.75 Me...
