Different explanations for the Sagnac effect are discussed. It is shown that this effect is a
consequence of the relativistic law of velocity composition and that it can also be explained …

The rapid development of all scientific disciplines and the growing sophistication of our tools
has resulted in the experimentalist having to choose between two alternatives: either he …

of gravitational potential on the ap-parent frequency of electromagnetic radiation by using
the sharply defined energy of recoil-free y rays emitted and absorbed in solids, as dis …

In 1988 the Mossbauer effect community completed 30 years of continual contribution to the
fields of nuclear physics, solid state science, and a variety of related disciplines. To …

The lifetimes of both positive and negative relativistic (γ= 29.33) muons have been
measured in the CERN Muon Storage Ring with the results τ+= 64.419 (58) µs, τ−= 64.368 …

Recoil-free resonant absorption of the 14.4-keV γ ray in Fe 57 has been employed to
measure the effect of gravity over a 75-ft vertical path in the Jefferson Laboratory, in an …

We experimentally investigate an optical frequency standard based on the 467 nm (642
THz) electric-octupole reference transition S 1/2 2 (F= 0)→ F 7/2 2 (F= 3) in a single trapped …

Using an ultracentrifuge rotor, the shift of the 14.4-keV Mössbauer absorption line of Fe 57 in
a rotating system was measured as a function of the angular velocity ω. An Fe 57 absorber …

Various statements identified with the principle of equivalence are not acceptable because
they are either not generally valid or are simply the definition of an inertial coordinate …

The transmission of resonance radiation emitted from a source of finite thickness and
passing through an external resonance absorber is discussed. The transmission integral is …
