Pre-Ionization in the slow θ Pinch

On Pre-θ-Open Sets and Two Classes of Functions

Θ ∗ partner to the Θ ( 1540 ) baryon

If the exotic baryon Θ(1540) is udud¯ s with J P = 1 2 + , we predict that there is a Θ * (1540− 1680) with J P = 3 2 +. The width Γ(Θ * → KN) is at least a factor of three larger than Γ(Θ). The possibilities of Θ * → KN π or Θγ via M 1 and E2 multipoles are discussed. A major plank in establishing the constituent quark model was the absence of baryons with strangeness +1. The announcement of s...

Electron density and ionization dynamics in an imploding z-pinch plasma

The time-dependent radial distributions of the electron and ion densities during the implosion phase of a gas-puff z-pinch plasma are determined from measurements of continuum radiation, as well as time-dependent collisional-radiative analysis of the observed particle ionization history in the plasma. It is shown that during the 140-ns-long time interval close to the end of the 620-ns-long impl...
