Measurement of the fusion probability, PCN, for hot fusion reactions
Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, PCN, i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and the survival of the completely fused system against fission. ...
متن کاملLow Energy Nuclear Fusion Reactions in Solids
The DD fusion reactions in various materials have been studied, and enhancements in the rate of the D(d,p)T fusion reaction over the Gamow function were clearly seen in the materials. Of particular interest is the fact that the reaction rate of the D+D reactions at 2.5 keV in PdO is 60 times (and in Pd 10 times) larger than in Ti, and the deduced screening energy amounts to 600 eV (300 eV). Fur...
متن کامل"Subbarrier fusion reactions with dissipative couplings"
Using the random matrix model, we discuss the effect of couplings to non-collective states on the penetrability of a one dimensional potential barrier. We show that these non-collective excitations hinder the penetrability and thus smear the barrier distribution at energies above the barrier, while they do not affect significantly the penetrability at deep subbarrier energies. The energy depend...
متن کاملSmall Effects in Astrophysical Fusion Reactions
We study the combined effects of vacuum polarization, relativity, Bremsstrahlung, and atomic polarization in nuclear reactions of astrophysical interest. It is shown that these effects do not solve the longstanding differences between the experimental data of astrophysical nuclear reactions at very low energies and the theoretical calculations which aim to include electron screening. Typeset us...
متن کاملFusion Reactions in Multicomponent Dense Matter
We analyze thermonuclear and pycnonuclear fusion reactions in dense matter containing atomic nuclei of different types. We extend a phenomenological expression for the reaction rate, proposed recently by Gasques et al. [11] for the one-component plasma of nuclei, to the multi-component plasma. The expression contains several fit parameters which we adjust to reproduce the best microscopic calcu...
