New relations between Borel sum rules for the magnetic moments of the Σ<Superscript>0</Superscript> and Λ hyperons

New relations between the Borel sum rules in QCD for the magnetic moments of the Σ⁰ and Λ hyperons are derived. It is shown that, on the basis of the sum rule for the magnetic moment of the Σ⁰ hyperon, one can directly obtain the corresponding sum rule for the magnetic moment of the Λ hyperon, and vice versa, as well as the corresponding sum rule for the Σ⁰ → Λ_γ transition.     

A terawatt pulse-power generator with a microsecond plasma-openingswitch

A review of the first experiments with the GIT-4 generator is given. GIT-4 is based on the results obtained previously on Gamma (1985) and Marina (1986) generators and has operated since December 1986. GIT-4 is designed to test the concept of a terawatt pulsed-power generator based on the direct charging of an inductive storage from a Marx primary store using a plasma-opening switch (POS) at currents up to several mega-amperes. Such generators need a POS with essentially microsecond conduction times. In the experiments reviewed, output powers up to 2.5 TW in the POS region were obtained at current levels up to 1 MA
