Some Constacyclic Codes over Finite Chain Rings
For an -th power of a unit in a finite chain ring we prove that
-constacyclic repeated-root codes over some finite chain rings are
equivalent to cyclic codes. This allows us to simplify the structure of some
constacylic codes. We also study the -constacyclic codes of
length over the Galois ring
On {\gamma}-rigid regime of the Bohr-Mottelson Hamiltonian in the presence of a minimal length
A prolate {\gamma}-rigid regime of the Bohr-Mottelson Hamiltonian within the
minimal length formalism, involving an infinite square well like potential in
{\beta} collective shape variable, is developed and used to describe the
spectra of a variety of vibrational-like nuclei. The effect of the minimal
length on the energy spectrum and the wave function is duly investigated.
Numerical calculations are performed for some nuclei revealing a qualitative
agreement with the available experimental data.Comment: 8 pages, 2 tables, 6 figures (preprint with corrected typos and a
