Low-energy magnetic dipole strength in cadmium isotopes

This study numerically investigates the mixed convection of ferrofluids in a partially heated lid driven square enclosure. The heater is located to the left vertical wall and the right vertical wall is kept at constant lower temperature while other walls of the cavity are assumed to be adiabatic. The governing equations are solved with Galerkin weighted residual finite element method. The influence of the Richardson number (between 0.01 and 100), heater location (between 0.25 H and 0.75H), strength of the magnetic dipole (between 0 and 4), and horizontal location of the magnetic dipole source (between-2H and-0.5H) on the fluid flow and heat transfer are numerically investigated. It is found that local and averaged heat transfer deteriorates with increasing values of Richardson number and magnetic dipole strength. The flow field and thermal characteristics are sensitive to the magnetic dipole source strength and its position and heater location.

Single Formula

In previous papers, we examined the systematics of magnetic dipole transitions in a single [Formula: see text] shell. We here extend the study to large space calculations. We consider the nuclei [Formula: see text]Ti, [Formula: see text]Ti and [Formula: see text]Cr. In this paper, we focus on the [Formula: see text] strength as a function of excitation of energy. The initial state is the lowest [Formula: see text] state in a specified nucleus. The final states are [Formula: see text] [Formula: see text], all in one plot, and [Formula: see text] [Formula: see text] in another. The initial figures have points all over the map although there is a suggestion of an exponential trend. To reduce clutter, we perform binning operations in which the summed strength in a given energy interval is represented by a single point. The new binning curves show more clearly the exponential fall of [Formula: see text]’s with energy.
