Angular distribution of rays from the p-wave resonance of Sn

J. Koga, S. Takada, S. Endo +14

The neutron energy-dependent angular distribution of rays from reaction was measured with germanium detectors and a pulsed neutron beam. The angular distr…

Is quantum teleportation beyond horizon possible?

Jun-ichirou Koga, Kengo Maeda

We ask whether quantum teleportation from the outside to the inside of a horizon is possible, using entanglement extracted from a vacuum. We first calculate analytically, within th…

Neutron lifetime measurement with pulsed cold neutrons

K. Hirota, G. Ichikawa, S. Ieki +26

The neutron lifetime has been measured by comparing the decay rate with the reaction rate of He nuclei of a pulsed neutron beam from the spallation neutron source at the Japan…
