In this paper we construct and give an analysis of the global convergence and local superconvergence properties of polynomial collocation solution u ∈ S m+d(ZN ) of Volterra integral equations with… (More)

The reliability of different electrode admittance equations in the case of the Ag/Ag I electrode is critically discussed. It is shown that the admittance equation already derived for the' metal… (More)

Charge transfer, electronic excitation, and ionization are three major categories of events that occur in an ion-atom collision [1]. Due to the Coulomb force, electrons from the neutral target may be… (More)

Superallowed 0 → 0 beta decay between T=1 analogue states has been a subject of continuous and often intense study for five decades. The ft values of such transitions are nearly independent of… (More)

Because of angular-momentum conservation, superallowed β decay between 0(+) analog states involves only the vector part of the weak interaction, so its measured ft value can be used to determine the… (More)

We report the first branching-ratio measurement of the superallowed 0+→0+β transition from Ca38. The result, 0.7728(16), leads to an ft value of 3062.3(68) s with a relative precision of ±0.2%. This… (More)

The possible orrgins of frequent deviations from the calculated and experimentally obtained values of the Warburg parameter of the Ag/AgI electrode are discussed. Following the considerations of… (More)
