Various industries have turned their attention to the study of metal behaviour at cryogenic temperatures. The conventional devices 1-4 for tensile testing require elaborate preparation and complicated set-ups involving vacuum, leakproof sealing, shields etc. A thorough study was made at the Indian I

โฆ Synopsis
Equivalence principle is an important cornerstone of general relativity and metric theories of gravity. To test the equivalence for nuclear-polarized bodies, we propose to use intermetallic compounds of Pr and Cu suitably polarized and magnetically shielded as our polarized bodies. We present the scheme of our experiment, and aim at a precision of 1O-5-1O-8 on the equivalence of polarized nuclei.
