Book excerpt: The study of nuclei far from beta stability is hampered greatly when the nuclide of interest decays in a manner identical to that of a nuclide produced in greater yield in the same bombardment. One solution to this problem is through the use of an on-line mass separator. Development of the Berkelely helium-jet fed on-line mass separator RAMA is discussed as applied to studies of the A = 4n, T/sub z/ = -2 nuclides. RAMA (Recoil Atom Mass Analyzer) has typical efficiencies of 0.1% for approx. 75 elements with melting points less than or equal to 2000°C. This efficiency permits decay studies to be readily performed on nuclei with production cross sections greater than or equal to 500 .mu.b for .gamma.-ray spectroscopy and greater than or equal to 1 .mu.b for discrete energy charged particle spectroscopy. The mass range on the normalized RAMA focal plane is +- 10%. The quoted efficiency is for a mass resolution of M/.delta. M approx. 300. RAMA has been used to observe two members of the A = 4n, T/sub z/ = -2 series of beta-delayed proton emitters, 2°Mg and 24Si. Observation of beta-delayed protons from a mass-separated sample of 2°Mg(t12 approx. 95 ms) establishes the mass-excess of the lowest T = 2 (0/sup +/) state in 2°Na (13.42 +- 05 MeV), thereby completing the mass twenty isospin quintet. A similar measurement of the decay of 24Si (t12 approx. 100 ms) establishes the mass-excess of the lowest T = 2 (0/sup +/) state in 24Al (5.903 +- 0.009 MeV). The mass 24 isospin quintet is incomplete because the mass of 24Si remains unknown. In both cases, excellent agreement is obtained using only the quadratic form of the isobaric multiplet mass equation (IMME). 79 references.

Book excerpt: Results from the RAMA-88 system at the Lawrence Berkeley Laboratory are being used to design a new helium-jet and ion source system for the UNISOR project. This system should complement the existing integrated target-ion source to extend UNISOR's capabilities to include a majority of the chemical elements. This fast transport helium-jet system should permit studies of nuclides with half-lives down to 50 ms.
