Possible anomalous interactions of ultracold neutrons
Artem'ev V. A.
Under conditions such that the energy of ultracold neutrons is quantized in a gravitational field g and the motion of the neutrons is two-dimensional, their elastic cross section is <χ ν ~ 1. The neutron-emission channel is suppressed in nuclear reactions with ultracold neutrons. An n2 molecule might form if the motion of the neutrons were one-dimensionaL
