We consider some special reductions of generic Darboux-Crum dressing formulas and of their difference versions. As a matter of fact we obtain some new formulas for Darboux-Pöschl-Teller potentials, their difference deformations and the related eigenfunctions.
The leader operators of the (d + 1)-dimensional relativistic rotating oscillators Abstract The main pairs of leader operators of the quantum models of rela-tivistic rotating oscillators in arbitrary dimensions are derived. To this end one exploits the fact that these models generate Pöschl-Teller radial problems with remarkable properties of supersymmetry and shape invariance.
The origin and nature of a special nonlinear supersymmetry of a reflectionless Pöschl-Teller system are explained by the Aharonov-Bohm effect for a nonrelativistic particle on AdS2. A key role in supersymmetric structure appearing after reduction by a compact generator of the AdS2 isometry is shown to be played by discrete symmetries related to space and time reflections in the ambient Minkowsk...
The properties of charge-exchange excitations of 208Pb with ∆L = 0, i.e., the isobaric analog and Gamow-Teller resonances, are studied within a self-consistent model making use of an effective force of the Skyrme type. The well-known isobaric analog case is used to assess the reliability of the model. The calculated properties of the Gamow-Teller resonance are compared with recent experimental ...
The Gamow–Teller β decays of the neutron-deficient indium isotopes 104–107In have been investigated by using total absorption γ -ray spectrometry on mass-separated sources. The experimental Gamow–Teller strength, deduced as a function of the excitation energy in the daughter nuclei 104–107Cd, is compared to shell-model predictions. 2001 Elsevier Science B.V.

The renormalization of the weak charge-changing hadronic current as a function of the reaction energy release is studied at the nucleonic level. We have calculated the average quenching factors for each type of current (vector, axial vector and induced pseudoscalar). The obtained quenching in the axial vector part is, at zero momentum transfer, 19% for the sd shell and 23% in the f p shell. We ...
