On the basis of the fundamental provision of general relativity about the equality of inertial and gravitational masses and the equivalence of kinematic and gravitational acceleration, a negative answer is given to the question posed in the title. (laser applications and other topics in quantum electronics)
We discuss the concept of remote inspection of the isotopic composition of objects in space by products of nuclear reactions (including the fission of heavy isotopes), initiated by directed accelerated beams of ultracold neutrons. Despite the partial unavailability of quantitative estimates of specific situations, the proposed approach is internally consistent. We emphasise the urgency of development the problem in question and offer directions for further research.
We discuss the physical feasibility of association of particles noninteracting with each other, which arises in accordance with the uncertainty relation under the 'corporate' spatial confinement of the particle ensemble as a whole. Investigation is conducted by the example of an ensemble of ultracold neutrons placed in a common potential well of infinite depth. We present quantitative estimates and indicate the expected properties of the arising crystal-like spatially periodic structures.
