Abstract
We investigated before the possibility of modifying alpha decay rate by the influence of a laser radiation upon a nucleus. We showed that the laser radiation with the extreme achievable intensity slightly modifies the total rate of alpha decay. A different result may be probably obtained if it use synchrotron radiation for the irradiation of an alpha-active nucleus. At present, synchrotron radiation from the third generation synchrotrons has high brilliance, the photon energy may reach 200–300 keV and, in the future, it may be larger. These energies are comparable with nuclear ones and the effect from the influence of the synchrotron radiation upon alpha decay could be more significant. As it turned out, the change of the alpha decay rate of 238U isotope into the synchrotron radiation field from the third generation synchrotrons will be negligible.
Highlights
The fundamental problem of external influence on various physical processes in a substance, as well as in its individual structural elements, is one of the most pressing problems of modern physics
We study the possibility of influencing on the alpha decay rate by the synchrotron radiation (SR) field generated by third-generation synchrotrons
Using the formula (6) for the penetrability of the barrier P, we estimate the change in its magnitude if the alpha particle energy Eα is increasing by 200 keV in the electromagnetic field
Summary
The fundamental problem of external influence on various physical processes in a substance, as well as in its individual structural elements (molecules, atoms and atomic nuclei), is one of the most pressing problems of modern physics. For the 238U isotope (Z = 92, Eα = 4.27 MeV) with an intensity of laser radiation of 1028 W/cm2, this acceleration is no more than 2% (hereinafter Z is the charge number of the parent nucleus; Eα is the energy of the emitted alpha particle).
