TL;DR: In this article, lifetime measurements of the Ru-100 nucleus have been performed using the recoil distance Doppler shift technique as well as the DOP shift attenuation method, and the lifetimes of the yrast 2(+, 4(+), and 8(+) states were determined.

TL;DR: In this paper, the Larmor frequency of neutrons in a weak magnetic field using the Ramsey resonance technique was measured and the results showed that a nonzero cosmic axial field, violating rotational symmetry would induce a daily variation of the precession frequency.
Journal ArticleDOI

Yasuo Tomita,Akihisa Kageyama,Yuko Iso,Koichi Umemoto,Atsushi Kume,Ming Liu,Christian Pruner,Tobias Jenke,S. Roccia,Peter Geltenbort,Martin Fally,Jürgen Klepp +11 more
TL;DR: In this paper, the authors demonstrate the use of nanodiamond in constructing holographic nanoparticle-polymer composite transmission gratings with large saturated refractive-index modulation amplitudes at both optical and slow-neutron wavelengths.
Journal ArticleDOI
