Ionization Of P Atom, P2 And PC Molecules By Electron Impact: Theoretical Studies

Being a biogenic element atomic Phosphorus is one of the significant constituents of the universe . Gulick  found a pivotal role of phosphorus in the origin of life. The phosphorus-containing molecules like PH, PC and PN radicals, have been observed in interstellar gas clouds [3 - 5] and they are proposed to be present under appropriate conditions. Phosphorous hydrides having numerous applications, are detected in cool stellar atmosphere  and circumstellar envelopes. Thus, the present paper addresses the electron impact processes of atomic phosphorus and its diatomic compounds. Ground and metastable states of Atomic P give rise to the probability of presence of metastable state in the atomic beam used for cross section measurement . We have employed the well- known Spherical Complex Optical Potential (SCOP) formalism to calculate total inelastic cross sections. The semi-empirical CSP-ic method is used to extract total ionization cross section Qion from total inelastic cross section . A variant CSP-ic approach is also attempted for these targets.
Keywords- Phosphorus, electron impact ionization, complex potential
