• Selection Rules for electric dipole transitions: ∆L = ±1, ∆S = 0, ∆J = 0, ±1 but not J = 0 to 0. Fine Structure: Atom in Magnetic Field • Selection Rule for weak field: ∆MJ = 0, ±1 but not from 0 to 0...
Since data assessment is in general a long-term activity, it is limited by contemporary funding time scales that are mostly short-term and project-based; its sustainability is consequently always fragile. In this respect, we are exploring the feasibility of a self-sustainable model based on an ...
