The doubly excited 1,3 P e meta-stable bound states and resonance states of helium embedded in weakly coupled plasmas are calculated using Slater orbital basis functions. The plasma effects are taken care of by using the screened Coulomb potential obtained from the Debye model. We have calculated the 2pnp 1 P e (n = 3, 4) and 2pnp 3 P e (n = 2, 3, 4) meta-stable bound state energies of He in plasmas for various Debye lengths. In addition, a total of ten resonances (five each for 1 P e and 3 P e states) below the N = 3 He + thresholds has also been obtained by calculating the density of states using a stabilization method. For the 1 P e states, this includes three members from the 3pnp (n = 4, 5, 6) series, and two members from the 3dnd (n = 4, 5) series. For the 3 P e state, this includes three members from the 3pnp (n = 3, 4, 5) series, and two members from the 3dnd (n = 3, 4) series. The resonance energies and widths for the 1,3 P e resonances for different screening parameters below the He + (3S) threshold are reported along with the eigen-energies of the 1,3 P e meta-stable bound states lying below the He + (2S) threshold.
