An omproved reaction rate formulation for charged-particle induced thermonuclear reaction of [sup 2]H(d,γ)[sup 4]He
The reaction rate formula utilized in compilations such as the Nuclear Astrophysics Compilation of Reaction Rates (NACRE) uses low energy approximation due to temperatures in stars are in the region of a few keVs.

| description |
The reaction rate formula utilized in compilations such as the Nuclear Astrophysics Compilation of Reaction
Rates (NACRE) uses low energy approximation due to temperatures in stars are in the region of a few keVs. Most
nuclear reaction experiments were done in MeV range and the interior temperatures of massive stars are ~ 10^9 K. Hence
an improved formulation for calculating the nuclear reaction rate that is applicable to high temperatures is discussed in
this work. The exact tunneling probability that is applicable for all energies is obtained by solving the Schrödinger
equation. This yields an enhanced expression for the astrophysical S-factor for calculating the thermonuclear reaction
rate at high temperature. The thermonuclear reaction rate from this work is applied to the 2H(d,γ)4
Keywords: coulomb energies, interaction and reaction cross sections, fusion reactions
He reaction and is
compared with the NACRE compilation. This improved reaction rate can be included in the nuclear reaction network in
a Big Bang nucleosynthesis (BBN) code or a stellar nuclear network code. |
