| General description: | The structure of tantalum is body centered cubic (BCC) metal. It is a refractory metal; stable up to very high temperatures. Tantalum is ductile at room temperature and moderately ductile at cryogenic temperatures. Compton profile of highly pure thin elemental foil of tantalum was investigated using IGP type coaxial photon detector.1 |
