摘要：

Lines of the kaonic x-ray spectra of 24 elements ranging from Z=17 to Z=92 have been measured. Kaons are absorbed at the nuclear surface from circular orbits. The sudden cutoff of transitions to successively lower principal quantum numbers at certain values of Z indicates that nuclear matter (probably neutrons) extends above the conventional nuclear surfaces. A peak in one of the spectra corresponds to x rays from - hyperonic atoms. © 1969 The American Physical Society.
