Initial steps are presented on the cranking of the Semimicroscopic Algebraic Cluster Model (SACM). This permits to treat Hamiltonians which do not present a dynamical symmetry.

This essay continues the investigation of an earlier article, also published in this journal, by examining artistic representations of Cuauhtémoc in the post-revolutionary period, and especially after 1940, when the figure of the last Aztec king became widely and variously…

The SU(1,1) coherent states of Barut and Girardello can be interpreted as Bessel-Gauss states that are time-dependent solutions of the Schrödinger equation. In this article, some basic properties of these states and their related operators are analyzed.

The potentialities of Double Beta Decay experiments in the field of neutrino study are here discussed. Sensitivity and results are compared with the information coming from oscillation, cosmology and beta decay measurements.

We describe the basic mechanisms responsible for nuclear bulk properties and shell formation incorporated in the Duflo Zuker models. The emphasis is put on explaining why functionals of the occupancies can be so efficient in accounting for data with minimal…

Some errors in a recent paper (Rev. Mex. Fis. E 53 (2007) 112) dealing with the Noether theorem are pointed out

We present a system with three equilibrium points which exhibit a single, double or triple scroll oscillation without introducing more equilibrium points. The study is based on one parameter of the nonlinear function which is the bifurcation parameter. With this…

The spectrum and separable eigenfunctions in parabolic coordinates for the bound states of the hydrogen atom, as well as their relation with the separable eigenfunctions in spherical coordinates, are obtained making use of the elementary theory of angular momentum.
