We have investigated the doubly excited 1,3Po resonance states of helium embedded in weakly coupled plasmas. A screened Coulomb potential obtained from the Debye model is used to represent the interaction between the charge particles. A correlated wavefunction consisting of a generalized exponential expansion has been used to represent the correlation effect. A total of 18 resonances (9 each for 1Po and 3Po states) below the n = 2 He+ thresholds has been estimated by calculating the density of… CONTINUE READING
