The spectrum of internal conversion electrons emitted by Th/sup 229/ (daughter nucleus of U/sup 233/) was studied in a beta spectrometer with a toroidal magnetic field in conjunction with an e- alpha coincidence circuit. The existence of a rotational level which corresponds to the ground level of Th/ sup 229/ was confirmed. The energies of the rotational levels were determined with better accuracy. Gamma transitions starting from some new levels (29.1, 71.4, 320.0, and 366.0 kev and apparently 131.0 kev) were detected and investigated. Some refinements were introduced in the U/sup 233/ alpha spectrum. The level scheme of Th/sup 220/ is discussed. (auth)
