Book excerpt: Using primarily a 75-cm radius of curvature 60 deg symmetrical electromagnetic analyzer, a study of the complexity of the following alpha spectra was made: Es253, Cf246, Cm244, Am243, Pu/sup 236,242/, Pa231, Th/sup 227,230/, Ac225, At2°9 and Po2°6. An investigation of the gamma rays associated with the following isotopes was also madei 236, and Pa231. Decay schemes have been suggested for most of the isotopes included in this study. Those for the even-even isotopes were found to conform well with the previously existing systematics for that group of nuclides. Many of the decay features of the odd-mass isotopes seemed to conform well with presently expanding theories. (auth).
