Transition Probabilities, Oscillator and Line Strengths in Sc XIX

East European Journal of Physics (2024)

Zaheer Uddin Muhammad Kaleem Saba Javaid Roohi Zafar

Scandium XIX ion is a member of the isoelectronic sequence of Li-like ions. Numerical coulomb approximation and quantum defect theory have been used to calculate energies, quantum defects & transition probabilities, oscillator, and line strengths of Sc XIX ion for the transitions ns → mp, np → ms, np → md, and nd → mp Rydberg series. The energies of Sc XIXX ions up to n = 5 are given in the NIST database and the literature. We used quantum defect theory and determined the energies and quantum defects up to n = 30. The energies and quantum defects of 125 levels are reported for the first time. Sc XIX ion's transition probabilities, oscillator, and line strengths were compared with the corresponding values in the NIST database of spectral lines. The NIST database contains data of only seventy-six spectral lines. Only six spectra lines have percent uncertainties of more than 10%. The results of the remaining seventy spectral lines agree well with the NIST values. Almost 1800 transition probabilities, oscillators, and line strengths are new.

A study of the hyperfine structure of Ta I lines based on Fourier transform spectra and laser-induced fluorescence

Physica Scripta (2009)

P. Głowacki Zaheer Uddin G. Guthöhrlein Laurentius Windholz J. Dembczyński

The hyperfine structure of several spectral lines of the tantalum atom has been investigated by laser excitation in the spectral range 4180–7000 Å. We report the discovery of 14 new energy levels of even parity and 21 new energy levels of odd parity. For the new levels, besides their wave number, their total angular momentum quantum number J, their parity, as well as their magnetic dipole and electric quadrupole hyperfine interaction constants A and B were determined. We classified altogether 73 lines by means of laser spectroscopy in a hollow cathode discharge, 52 of them by laser excitation and 21 via fluorescence decay. Additionally, 120 lines, observed in high-resolution Fourier transform spectra, were classified by using their wave numbers and their characteristic hyperfine patterns.

NUTRITION COMPARISON BETWEEN GENUS OF APPLE (MALUS SYLVESTRIS AND MALUS DOMESTICA) TO SHOW WHICH CULTIVAR IS BEST FOR THE PROVINCE OF BALOCHISTAN

Muhammad Aziz Mervat M. Anwar Zaheer Uddin Hiba Amanat Huma Ayub

Apple farming cultivation is expanding in Balochistan. But there is no scientific study present on this subject which apple genus is beneficial according to nutritional point of view. This is the main object of this study to evaluate the nutritive composition of different Genus of apples. Keeping this objective in mind two different genus of apples were selected i.e. Malus Sylvestris and Malusdomestica. To know the percentage composition of Moisture, Ash, Brix, Fat, Pectin, Fiber, Protein, Total sugar, Calcium, Sodium, Potassium, Phosphorus, Magnesium, Iron, Fat and water soluble vitamins in apples, they have been quantitatively analyzed using Atomic Absorption Spectroscopy, Flame Photometry and other chemical methods. The nutritional assessment results show that Malusdomestica (Discovery) has an edge over Malus sylvestris (Red Sentine). The percentage of Moisture, Potassium and Ascorbic acid is slightly high in Malus Sylverstris, On the other hand the Ash, Brix, Fat, Pectin, Fiber, Protein and Total sugar percentages are comparatively high in Malusdomestica and show a difference 0.15, 3.9, 0.48, 0.4, 5.5, 0.25, 8.25 of percentages respectively. The concentration of Calcium 20.79, Sodium11.01 ,Phosphorus16.4 , Magnesium 14.62, Iron 7.23 and Vitamin A 0.97 ( mg/100gm) in Discovery apples and show a

Teaching physics online through spreadsheets in a pandemic situation

Physics Education (2020)

Majid Iqbal Fayzan Ahmed Arshad Iqbal Zaheer Uddin

Abstract Teaching physics with simulations is an interactive way of teaching physics to students. In recent years, many scientists have used spreadsheets for simulating topics in physics and other fields. Excel is a piece of user-friendly spreadsheet software. In this lockdown situation, spreadsheets are good tools to teach physics experiments online through simulation. In this paper, we present two examples which are simulated on an Excel spreadsheet. The examples include simulations of image formations by spherical mirrors with a ray diagram and a demonstration of Malus’ law.
