Quantum mechanical calculations have been accomplished to study the dynamics of the reaction: p + H(1s) → H(nlm) + p in dense semi-classical hydrogen plasma. Interactions among the charged particles in plasma are represented by a pseudopotential which takes care of the collective effects at large distances and quantum effect of diffraction at small distances. Various capture cross sections are computed for the incident proton energy lying within 10 to 500 keV by applying a distorted wave method which uses a variationally determined closed-form wave function of hydrogen atom. Moreover, an inclusive study is made to explore the effects of screening of plasma and quantum diffraction on various capture cross sections for a wide range of thermal Debye length and de Broglie wave length. It has been found that various cross sections suffer considerable changes due to varying Debye length and de Broglie wave length.

“…The pseudopotential () includes the collective events and the screening effects in it, and properly describes particle interaction in CNP for 0 ≤ γ ≤ 4.0. Note that this potential takes the form of the Debye‐Huckel potential, when γ → 0, that is, in the weak limit of non‐ideality. The pseudopotential () has been used in a number of studies relating to CNP [32–35]. In this paper, we use the pseudopotential () to describe the interaction potential among the charged particles in He embedded in CNP.…”

Properties of the ground state of the helium atom embedded in classical nonideal plasmas have been investigated within the framework of variational method. The background plasma is described by a pseudopotential which has been deduced from the sequential solution of Bogolyubov's hierarchy equations. An extensive trial wave function is employed in Rayleigh-Ritz variational principle to compute various quantities associated with the ground state of helium atom quite accurately. A detailed study is made on the changes in those quantities introduced by the varying nonideality of the plasma in a wide range. In particular, special emphasis is made to study the stability of the atom in the plasma by computing the critical values of screening parameter and nonideal parameter accurately. To the best of our knowledge, such a study on the stability of helium atom in classical nonideal plasmas is reported for the first time in the literature.

“…Note that in case of weak NI (γ → 0), the above pseudopotential appropriately reduces to the Debye-Huckel potential which represents the screened interaction in WCPs. So far, the pseudopotential (1) has been used in a number of investigations relating to NICP [20][21][22][23][24][25][26][27][28][29][30][31].…”

The eﬀects of non-ideality of plasma on the energy levels of the hydrogen molecular ion (H2 + ) have been investigated by computing accurate binding energies of the ion under non-ideal plasma. The screened interaction potential in the plasma has been described by a pseudopotential which is derived from a solution of Bogolyubovs hierarchy equations by ignoring the eﬀects of quantum degeneracy. Changes in the energy of the ground state and the ﬁrst excited state along with the expectations of some important quantities associated with the ground state of H2 + due to the non-ideality of the plasma varying within a wide range have been studied in details. Special emphasis is made on the stability of the ion under varying non-ideality of plasma. Moreover, appearance of the Borromean window and its changes with varying non-ideality are also been discussed in details.
