In a paper appearing in this issue of Physics Letters A, Kowalski raises some critical comments on the experiment [F. Cardone, R. Mignani, A. Petrucci, Phys. Lett. A 373 (2009) 1956] that we carried out by cavitating a solution of…
In a number of recent articles in this journal F. Cardone and collaborators have claimed the observation of several striking nuclear phenomena which they attribute to "piezonuclear reactions". One such claim [Phys. Lett. A 373 (2009) 1956]…

In a recent article F. Cardone et al. [Phys. Lett. A 373 (2009) 1956] have claimed that subjecting a solution of 228Th to cavitation leads to a "transformation" of the thorium nuclei that is 104 times faster than the normal nuclear decay…
In this paper, we deal with the subject of piezonuclear reactions, namely nuclear reactions (of new type) triggered by pressure waves. We discuss the experimental evidences obtained in the last two decades, which can be summarized…
We show that cavitation of a solution of thorium-228 in water induces its transformation at a rate 10000 times faster than the natural radioactive decay would do. This result agrees with the alteration of the secular equilibrium of…
Subjecting a solution of 228Th to ultrasound (20 kHz, 100W), Cardone et al. [Phys. Lett. A 373 (2009) 1956] claim to observe an increase in the transformation or decay rate of 228Th by a factor of 104. The evidence provided seems however…
Reactions are an important tool to study nuclear structure and for extracting reactions relevant for astrophysics. In this paper we focus on deuteron induced reactions which can provide information on neutron shell evolution as well as…
As a desirable supplement to the reaction $pp \to pp2\gamma$, proposed earlier (nucl-th/9712064 and references therein) to probe for the NN--decoupled dibaryon resonances we suggest to use for the same goal the radiative capture processes…
We report the results obtained by cavitating water solutions of iron salts (iron chloride and iron nitrate) with different concentrations at different ultrasound powers. In all cases we detected a neutron radiation well higher than the…
Some critical comments and remarks on the article "Comparison of two experiments on radiative neutron decay" by R.U.Khafizov et al., published in Physics of Atomic Nuclei.
We show that cavitation of a solution of thorium-228 in water does not induce its transformation at a faster rate than the natural radioactive decay. We measured the activity of a thorium-228 solution in water before, and after, it was…
The methods used in the evaluation of the neutrino-nucleus cross section are reviewed. Results are shown for a variety of targets of practical importance. Many of the described reactions are accessible in future experiments with neutrino…
Given the drastic progress achieved during recent years in our knowledge on the decay and nuclear properties of the thorium isomer 229mTh, the focus of research on this potential nuclear clock transition will turn in the near future from…
In recent time the deuteron structure at short distances is often treated from the point of view nonnucleonic degrees of freedom. In this paper the measurements of T-odd polarization observables using tensor polarized deuteron beam and…
We make predictions of the effects of acceleration on decay rate for three benchmark processes spanning alpha, beta and isomeric decay. These processes are observed to require lower acceleration than that required by previously studied…
The purpose of this paper is to place side by side the experimental results of Piezonu- clear reactions, which have been recently unveiled, and those collected during the last twenty years of experiments on low energy nuclear reactions…
We briefly remind references and arguments, already discussed in the past, which confute erroneous claims in arXiv:1210.5501.
Despite its very short lifetime positronium provides us with a number of accurate tests of the bound state QED. In this note a brief overview of QED theory and precision experiments on the spectrum and annihilation decay of the positronium…
In this article, we perform an systematic study of the radiative transitions among the bottomonium states based on the heavy quarkonium effective theory, and make predictions for the ratios among the radiative decay widths of a special…
