What is there in a name?. Quite a lot if you think hard?
The magntic moment of a nucleus with non zero spin is often denoted by the Greek letter
pronounced "mu". The energy levels of a nucleus change when a nucleus with a finite magnetic moment is placed in a strong magneic field measured in Tesla's. We are developing new shell model codes to calculate, among other observables, the magnetic moment of a nucleus in any energy state. This will be done by running parts of the calculation in supercomputers with a few Tesla's, namely nVidia Tesla's. But how much will the minimum specification cost? Well it will cost less than $1700 for a one Tflop super computer. That's correct 1,000,000,000,000 Flops for $1700. The new codes will be based on your old faithful NuShell & NushellX see http://knollhouse.org .

We recommend Windows 7 Ultimate x64 as the preferred operating system for MuShellX. It has been developed on this operating system. Windows 7 is fast, stable and reliable. All code will be 64 bit.
At the heart of these codes is a completely new way of performing shell model calculations. We use a combination of some of the best conventional methods, often implemented in a completely novel way, combined with some of the best techniques used in NuShell and NuShellX along with some observations that states with distinct S can also egienstates with definite isospin T. We use a special seniority coupling method that ensures that the SDI interacion commutes with quasispin.
Test calculations with NuShell indicate some 75% os a realistic shell model Hamiltonian is already diagonal in the quasispin scheme when single particle energies are included,
