A flux tube model for glueballs
Masaharu Iwasaki, Shin-Ichi Nawa, Takayoshi Sanada +1
We calculate the mass spectrum and the decay widths of glueballs in the flux tube model. The glueball is assumed to be a closed flux tube. The breathing motion and the rotational m…
Influence of tunneling on electron screening in low energy nuclear reactions in laboratories
Sachie Kimura, Noboru Takigawa, Masanori Abe +1
Using a semiclassical mean field theory, we show that the screening potential exhibits a characteristic radial variation in the tunneling region in sharp contrast to the assumption…
Non-adiabatic effect in electron screening in fusion reactions at astrophysical energies
K. Hagino, N. Takigawa, M. Abe
We calculate the electron screening effect in low energy nuclear fusion reactions by taking non-adiabaticity of the tunnleing process into account. In order to investigate deviatio…
Thermal fission rate around super-normal phase transition
K. Hagino, N. Takigawa, M. Abe
Using Langer's method, we discuss the temperature dependence of nuclear fission width in the presence of dissipative environments. We introduce a low cut-off frequency to th…
