摘要：
A first-time study is made for the ground and excited states of plasma-embedded lithium atom in the presence of a homogeneous magnetic field by using the variational Monte Carlo method. The low-lying excited doublet states considered are 1s(2)ns, 1s(2)np, and 1s(2)nd states, whereas the used plasma potentials are the screened Coulomb (SCP) and exponential cosine screened Coulomb (ECSCP) potentials. The energy eigenvalues are assessed by choosing suitable trial wave functions, including the correlated (electron-electron repulsion) and spin parts, in addition to an effective plasma factor regarding the wave function of the ECSCP model. Using the two plasma models, an interesting relative ordering for the lithium atom reports the results.
