In this paper we present a scheme for constructing the coherent states of Klauder-Perelomov’s type for a particle which is trapped in Pöschl-Teller potentials.

A hidden nonlinear bosonized supersymmetry was revealed recently in Pöschl-Teller and finite-gap Lamé systems. In spite of the intimate relationship between the two quantum models, the hidden supersymmetry in them displays essential differences. In particular, the kernel of the supercharges of the Pöschl-Teller system, unlike the case of Lamé equation, includes nonphysical states. By means of L...

New calculations are presented for Gamow-Teller beta decay of nuclei near 100 Sn. Essentially all of the 100 Sn Gamow-Teller decay strength is predicted to go to a single state at an excitation energy of 1.8 MeV in 100 In. The first calculations are presented for the decays of neighboring odd-even and odd-odd nuclei which show, in contrast to 100 Sn, surprisingly complex and broad Gamow-Teller ...

A detailed model for the calculation of beta decay rates of the fp shell nuclei for situations prevailing in pre-supernova and collapse phases of evolution of the core of massive stars leading to supernova explosion has been extended for electron-capture rates. It can also be used to determine the half-lives of neutronrich nuclei in the fp/fpg shell. The model uses an averaged Gamow-Teller (GT)...

Relations between the total fl+ Gamow-Teller (GT+) strength and the E2 strength are further examined. It is found that in shell-model calculations for N = Z nuclei, in which changes in deformation are induced by varying the single-particle energies, the total GT+ or GT_ strength decreases monotonically with increasing values of the B (E2) from the ground state to the first excited jn = 2 + stat...

This paper clearly defines the problem to be discussed: if the distortion from the tetrahedral to D2d is caused by Jahn Teller. The introduction explains the reason for the assumption of Jahn Teller distortion using solid rational. The introduction for the possibility that this effect could be due to other factors is also involved in the introduction along with some compelling rationale to argu...

The aim of this study is to investigate the possibility of Saccharomyces cerevisiae as an alternative adsorbent for phenol removal from aqueous solution .The Saccharomyces cerevisiae was characterised by Brunauer Emmett Teller (BET) and Fourier transform (FT-IR). Adsorption properties of Saccharomyces cerevisiae towards phenol were systematically investigated, including pH effect, adsorbent dos...

We use the temperature of the structural phase transition to determine the Jahn-Teller (JT) coupling constant in the model derived for LaMnO3 which includes both the superexchange between S = 2 spins and the JT effect. We also investigate the dependence of the exchange constants on the value of the on-site Coulomb element U , and on the orbital ordering. Journal ref.: O. Sikora and A. M. Oleś, ...
