Loss rate of ultracold neutrons due to the absorption by trap walls in large material traps
Pavel D. Grigoriev, Vladislav D. Kochev, Victor A. Tsyplukhin +2
The most accurate neutron lifetime measurements now use the material or magnetic traps of ultracold neutrons (UCN). The precision of these experiments is determined by the accuracy…

A method for measuring deviation from Lambert diffuse scattering law of ultracold neutrons on material walls
P. D. Grigoriev, V. D. Kochev, V. A. Tsyplukhin +2
Modeling the motion of ultracold neutrons (UCNs) is crucial for assessing their losses, accurately measuring their lifetime, and describing other experiments. In material traps, it…

3D-2D crossover and phase shift of beats of quantum oscillations of interlayer magnetoresistance in quasi-2D metals
Taras Mogilyuk, Pavel Grigoriev, Vladislav Kochev +2
Magnetic quantum oscillations (MQO) are traditionally applied to investigate the electronic structure of metals. In layered quasi-two-dimensional (Q2D) materials the MQO have sever…
