On the Temperature Role in the Tunneling Process at the Low-Energy Nuclear Fusion
Keywords:low-energy nuclear fusion, tunneling through the screened Coulomb barrier, temperature dependence of the tunneling rate
The temperature dependence of the coefficient of tunneling through the Coulomb barrier is estimated for nuclei of the hydrogen isotopes at comparatively low temperatures using a model of screened Coulomb interaction potential between the isotopes put inside an external oscillator potential well. The temperature dependences for the tunneling coefficient are calculated for pp-, pd-, pt-, dd-, and dt-processes at different screening radii. The probable role of pp-reactions is discussed.
