Green's function derivation of the thermal random phase approximation equations in open shell systems

The thermal Green's functions are used to derive the thermal random phase approximation (TRPA) in open shell systems. The TRPA in the Sn isotopes is studied for a separable quadrupole interaction as a function of the temperature. The matrix elements of quadrupole particle-hole and two-particle...
