X-ray spectra were observed from proton-induced excitation of monazite inclusions possessing both normal and giant pleochroic halos at E/sub p/ = 4.7 and 5.7 MeV. A complete elemental analysis of these spectra is reported for elements with Z > or = 26. Weak photopeaks are observed from monazite inclusions possessing giant halos which are absent from inclusions with normal halos, although limitations in spatial resolution of the proton beam prevented accumulation of statistically definitive data. Because of energy, width, and intensity anomalies, some of these weak photopeaks are not readily interpretable as x rays of ..gamma.. rays or known elements. Proposed evidence for superheavy elements is carefully examined. |
