The performance of an optically stimulated luminescent (OSL) passive dosimetry system named MicroStar reader manufactured by Landauer Inc and acquired in 2011 is assessed in this study. The assessment carried out is based on the results of the intercomparison (IC) exercises organised by the International Atomic Energy Agency in 2013 and 2021. The IC results show that this OSL reader can maintain good performance after long-term usage provided adequate maintenance and calibration operations are carried out. Moreover, this assessment also reveals the importance of using a higher number of measurements per data point for the non-linearity test of the IEC 62387 standard.

Technical performances of two optically stimulated luminescence readers including, a microStar reader and an Auto 200 reader both manufactured by Landauer, Inc. were studied by the National Radiation Protection Agency Dosimetry Laboratory using manufacturer and International Electrotechnical Commission requirements. The two reader tools demonstrated satisfactory results as they met all the requirements. The two readers showed similar performance for the overall uncertainty and the Coefficient of Variation tests. The microStar reader showed better performances for the linearity and quality control tests, whereas the Auto 200 reader has a lower limit of detection. Moreover, an average shift of 0.08 mSv exists when measuring the doses with the two readers.

The aim of this paper is to determine the behavior and statistical properties of non-relativistic heavy quarkonia interacting with the extended Cornel potential within a space-time generated by a cosmic-string. We extend the cornel potential by adding the inverse square potential plus the quadratic potential. We have calculated the energy eigenvalues and the corresponding eigenstates using the extended Nikiforov-Uvarov (NU) method. Then the thermodynamic properties like partition function, entropy, free energy, mean energy and specific heat capacity are calculated within the space-time of a cosmic-string. In the next step, we investigate the influence of the cosmic-string parameter on quantum states of heavy quarkonia and their statistical properties.

In this work, we study the collective Bohr Hamiltonian of triaxial nuclei within deformation-dependent mass formalism (DDM) using the new Anharmonic potential. The Schrödinger equation with Bohr Hamiltonian is separated into two parts and the [Formula: see text]-part is solved by mean of Nikiforov–Uvarov method to obtain the energy spectra. The [Formula: see text]-part is defined by a ring shape potential and solved with the same method. The energies and the [Formula: see text] transition rates for nuclide [Formula: see text]Pt are calculated and compared with the experimental data and with some others models in the same formalism.
