Abstract: | We considered the kaon absorption from atomic states into the nucleus. We found that the nuclear density probed by the atomic
kaon significantly depends on the kaon orbit. Then, we re-examined the meanings of the observed strengths of one-body and
two-body kaon absorption, and investigated the effects to the formation spectra of kaon bound states by in-flight (K
-, p) reactions. As a natural consequence, if the atomic kaon probes a smaller nuclear density, the ratio of the two-body absorption
at nuclear center is larger than the observed value in kaonic atoms, and the depth of the imaginary potential is deeper even
at smaller kaon energies as in kaonic nuclear states because of the large phase space for the two-body processes. This deeper
imaginary potential makes the signals of kaonic nucleus formation more unclear in the (K
-, p) spectra. |
