By using the analytical superasymmetric fission model it is shown that all "stable" nuclei lighter than lead with Z > 40 are metastable relative to the spontaneous emission of nuclear clusters. An even-odd effect is included in the Zero point vibration energy. Half-lives in the range 1040-1050 s are obtained for Z > 62. The region of metastability against these new decay modes is extended beyon...

Alternative splicing at position 3495 b yields SERCA2 (sarco/endoplasmic reticulum Ca2+ pump 2) RNA species, namely SERCA2a and SERCA2b which differ in 3'-end regions. This results in SERCA2b RNA being less stable. In vitro decay experiments show that, in the presence of protein extracts from nuclei of LVMs (left ventricular myocytes), the rate of decay of both SERCA2b RNA and synthetic RNA fro...

Neutrino decay in vacuum has often been considered as an alternative to neutrino oscillations. Because non-zero neutrino masses imply the possibility of both neutrino decay and neutrino oscillations, we present a model-independent formal treatment of these combined scenarios. For that, we show for the example of Majoron decay that in many cases decay products are observable and may even oscilla...

Nuclear spin systems in manganites, having separation of ferromagnetic and antiferromagnetic phases, which are manifested as two lines the NMR spectrum, studied. Taking into account Ising nuclear interaction, we obtain an analytical description Rabi oscillations free induction decay two-component when a radio-frequency pulse non-resonantly excites nuclei one magnetic phase resonantly other phas...

In nuclear physics, it is well known that the electromagnetic (Coulomb) interaction between final state products can drastically effect particle reaction rates. Near thresholds, for example, nuclear alpha decay is suppressed while nuclear beta decay is enhanced by final state Coulomb interactions. Here we discuss high energy physics enhancement and/or suppression of reactions wherein the potent...

We review our theoretical work on the dynamics of a localized electron spin interacting with an environment of nuclear spins. Our perturbative calculation is valid for arbitrary polarization p of the nuclear spin system and arbitrary nuclear spin I in a sufficiently large magnetic field. In general, the electron spin shows rich dynamics, described by a sum of contributions with exponential deca...

The first, to our knowledge, calculation of neutrinoless double beta decay (0νββ-decay ) matrix elements within the self-consistent renormalized Quasiparticle Random Phase Approximation (SRQRPA) is presented. The contribution from the momentum-dependent induced nucleon currents to 0νββdecay amplitude is taken into account. A detailed nuclear structure study includes the discussion of the sensit...

Nuclear super-allowed β decay has been used to obtain tight limits on the value of CKM matrix element Vud that is important for unitarity tests and, therefore, standard model. Current requirements precision are so intense effects formerly thought too small matter now considered relevant. This article a brief review personal efforts include strong interactions Fermi decay. First, I examine role ...
