Formally, the mixing ratio can be regarded as the relative strength of the E2 component vs. the M1 component of the electroamgnetic transitions.

In other words, the mixing ratio will show the magnitude and character of the transition: $\delta=\frac{\langle I_f||E_2|| I_i \rangle}{\langle I_f||M_1|| I_i \rangle}$

Thus, this dimensionless quantity shows that if $|\delta | <1$ then the transition will have an M1 character, while an electrice quadrupole E2 character will exhibit when $|\delta|>1$.

For the context of wobbling motion, the mixing ratio will tell:

• how much of the wobbling angular momentum is perpendicular to the rotational axis (E2 component).
• how much is along the main rotation axis (M1 component)
• Theory predicts a large E2 component in the ΔI = 1 inter-band transitions.

Initial setup for a developer oriented macOS

In this guide we will focus on the necessary steps, settings, and tools that are required in order to have an environment that is streamlined for development, research, and overal productivity; all while keeping an emphasiz on distraction-free and minimalism

OS level

• We will always try to keep the operating system at the latest available version (stable releases only), so the very first step would be to make sure that our system has all the OS updates installed
• At the time of writing this guide, my macOS version is Version 14.5 (23F79)

Executing Mathematica Scripts Within the Command-Line

This guide will show how to run Wolfram Mathematica scripts right from the command-line, without using the Frontend.

Setting up the console environment (MacOS)

Technically, a Mathematica script can be executed from the command line using the Mathematica Kernel.

After installation of the Wolfram Mathematica application, default location of that executable kernel should be at /Applications/Mathematica.app/Contents/MacOS:
