What Does CPSSR Stand For?

CPSSR stands for Coulomb Repulsion Perturbed Stationary State With Relativistic Effects

CPSSR, or Coulomb Repulsion Perturbed Stationary State With Relativistic Effects, refers to a theoretical framework used in quantum mechanics to examine the behavior of atomic and subatomic particles under the influence of Coulomb forces while accounting for relativistic effects. This approach is crucial for accurately modeling systems where classical mechanics fails to provide precise predictions due to the relativistic speeds of particles involved. CPSSR is particularly relevant in fields such as atomic physics, quantum chemistry, and materials science, where understanding electron interactions and stability near nuclear regions is essential.
