Anomalous Internal Pair Creation
Péter Kálmán, Tamás Keszthelyi
In recent electron-positron angular correlation measurements the observed significant enhancements relative to the internal pair creation at large angles was interpreted as indicat…
Photo-induced nuclear cooperation
Péter Kálmán, Tamás Keszthelyi
Reactions and especially the reaction $p…
Forbidden Nuclear Reactions
Péter Kálmán, Tamás Keszthelyi
Exothermal nuclear reactions which become forbidden due to Coulomb repulsion in the\ limit ($\lim_{\varepsilon \rightarrow 0}σ\left( \varepsilon \right)…
Effect of impurities on nuclear fusion
Péter Kálmán, Tamás Keszthelyi
Modification of nuclear reactions due to impurities in plasma is investigated. The hindering effect of Coulomb repulsion between reacting particles, that is effective in direct rea…
Cooperative internal conversion process by proton exchange
Péter Kálmán, Tamás Keszthelyi
A generalization of the recently discovered cooperative internal conversion process is investigated theoretically. In the cooperative internal conversion process by proton exchange…
Cooperative internal conversion process
Péter Kálmán, Tamás Keszthelyi
A new phenomenon, called cooperative internal conversion process, in which the coupling of bound-free electron and neutron transitions due to the dipole term of their Coulomb inter…
Charged particle assisted nuclear reactions in solid state environment: renaissance of low energy nuclear physics
Péter Kálmán, Tamás Keszthelyi
The features of electron assisted neutron exchange processes in crystalline solids are survayed. It is stated that, contrary to expectations, the cross section of these processes m…
Electron assisted reactions in metals
Péter Kálmán, Tamás Keszthelyi
The electron assisted low energy reactions in deuterized metals are investigated. It is shown that if a metal is irradiated with slow, free deuterons then the $e+d+d\rightarro…
Electron assisted neutron exchange process in solid state environment
Péter Kálmán, Tamás Keszthelyi
Electron assisted neutron exchange process in solid state environment is investigated. It is shown that if a metal is irradiated with free electrons then the …
Laser-assisted nuclear photoeffect reexamined
Péter Kálmán, Dániel P. Kis, Tamás Keszthelyi
The S-matrix element and the cross section of the laser-assisted nuclear photoeffect are recalculated in a gauge invariant manner taking into account the effect of the Coulomb fiel…
Near threshold laser-modified proton emission in nuclear photoeffect
Péter Kálmán, Dániel Péter Kis, Tamás Keszthelyi
The change of the probability of proton emission in nuclear photoeffect due to an intense coherent (laser) field is discussed near the threshold, where the hindering effect of the…
Resonance-like nuclear processes in solids: 3rd and 4th order processes
Péter Kálmán, Tamás Keszthelyi
It is recognized that in the family of heavy charged particle and electron assisted double nuclear processes resonance-like behavior can appear. The transition rates of the heavy p…
Nuclear processes in solids: basic 2nd-order processes
Péter Kálmán, Tamás Keszthelyi
Nuclear processes in solid environment are investigated. It is shown that if a slow, quasi-free heavy particle of positive charge interacts with a "free" electron of a metallic hos…
