In this paper, proton decay in a large nucleus is studied in the framework of SU{5) grand unification theory (GUT). By using a method based upon the Green s-function technique of many-body physics, nuclear effects on spectator and pole terms are computed. The decay width in the nucleus is found to be practically the same as in free space. However, nuclear effects are of considerable importance ...

In October 1934, at a meeting of the Osaka Branch of the PhysicoMathematical Society of Japan, Hideki Yukawa proposed a new theory of nuclear forces involving the exchange between neutron and proton of an electrically charged “heavy quantum”.l Yukawa’s theory is known today as the meson theory of nuclear forces and his “heavy quantum” is called the meson.2 The theory provided a fundamental expl...

— Comprehensive description of the phenomenology of the ββ decay is given, with emphasis on the nuclear physics aspects. After a brief review of the neutrino oscillation results and of motivation to test the lepton number conservation, the mechanism of the 0νββ is discussed. Its relation to the lepton flavor violation involving charged leptons and its use as a diagnostic tool of the 0νββ mechan...

We theoretically propose a scheme for verification of quantum Zeno effect (QZE) to suppress a decay process with Nuclear Magnetic Resonance (NMR). Nuclear spins are affected by low frequency noise, and so one can naturally observe non-exponential decay behavior, which is prerequisite in observing QZE. We also describe that a key component for QZE, namely measurements on the nuclear spin, can be...

We present some new results on heavy-element nuclear-structure properties calculated on the basis of the finite-range droplet model and folded-Yukawa single-particle potential. Specifically, we discuss calculations of nuclear ground-state masses and microscopic corrections, α-decay properties, β-decay properties, fission potential-energy surfaces, and spontaneous-fission half-lives. These resul...

Recent large-scale transcriptome analyses have revealed a large number of transcripts with low protein-coding potential, known as non-coding RNAs (ncRNAs). Many studies revealed that several long ncRNAs are involved in the regulation of genome organization and gene expression, or in the structural components of functional domains in the nucleus. As regulation of mRNA decay in the cytoplasm is c...

Theoretical predictions as well experiments performed at storage rings have shown that the lifetimes of ?-radionuclides can change significantly a function ionization state. In this paper we describe an innovative approach, based on use compact plasma trap to emulate selected stellar-like conditions. It has been proposed within PANDORA project (Plasmas for Astrophysics, Nuclear Decay Observatio...
