Abstract
By using the thermofield dynamics, we have calculated the effective coupling of nucleon-nucleon mesons by summing the three-lines vertices and the masses of nucleon and mesons by summing the corresponding self-energy diagrams of the Bonn potential model at finite temperature. Through the temperature dependence of effective couplings and the screening masses, we have extended the Bonn potential to finite temperature. © 1996 The American Physical Society.
