Measurement of theK-shell ionization probability across a wide resonance:Sr88(p,p0) at 6.06 MeV

We have measured the $K$-shell ionization probability across the 6.06-MeV resonance in ${}_{}{}^{88}{}_{}{}^{}\mathrm{Sr}$($p$,$p_0$) where the resonance width is large compared to the energy transferred to the electron. The results are found to agree quantitatively with the theory developed by Blair and Anholt. The effect of the time delay on the ionization probability, introduced by the nuclear scattering at the resonance energy, is discussed.
