Study of the neutron quantum states in the gravity field
Abstract.We have studied neutron quantum states in the potential well formed by the earth’s gravitational field and a horizontal mirror. The estimated characteristic sizes of the neutron waveExpand

Short-range fundamental forces
Abstract We consider theoretical motivations to search for extra short-range fundamental forces as well as experiments constraining their parameters. The forces could be of two types: 1)Expand

Search for quantum states of the neutron in a gravitational field: gravitational levels
Abstract The neutron could occupy quantum stationary states if it is trapped between the Earth's gravitational field on one side and the Fermi quasi-potential of a mirror on the other side. TheExpand

A measurement of the beta asymmetry in neutron decay with PERKEO II
The recent measurement of the electron asymmetry in neutron decay using the spectrometer PERKEO II is presented. In a preliminary analysis we arrive at the following result: A"!0.1189(8), implyingExpand

Observation of a triple correlation in ternary fission: is time reversal invariance violated?
Abstract In ternary fission, besides the two main fission fragments, a third (usually light) charged particle is emitted. A triple correlation has been studied involving the momenta for a specificExpand

GRANIT project: a trap for gravitational quantum states of UCN
Previous studies of gravitationally bound states of ultracold neutrons showed the quantization of energy levels, and confirmed quantum mechanical predictions for the average size of the two lowestExpand

Prospects for Studies of the Free Fall and Gravitational Quantum States of Antimatter
Different experiments are ongoing to measure the effect of gravity on cold neutral antimatter atoms such as positronium, muonium, and antihydrogen. Among those, the project GBAR at CERN aims toExpand

Particular features of ternary fission induced by polarized neutrons in the major actinides U-233,U-235 and Pu-239,Pu-241
Ternary fission in $(n,f)$ reactions was studied with polarized neutrons for the isotopes $^{233,235}\mathrm{U}$ and $^{239,241}\mathrm{Pu}$. A cold longitudinally polarized neutron beam wasExpand

The discovery of the neutron and its consequences (1930–1940)
Abstract In 1930, Walther Bothe and Herbert Becker performed an experiment, which was further improved by Irene and Frederic Joliot-Curie. These authors, however, misinterpreted their results andExpand
