STATE-DEPENDENT AND ISOTOPE-DEPENDENT CHARGE-TRANSFER OF N4-HYDROGEN IN ASTROPHYSICAL AND FUSION PLASMAS( WITH ATOMIC)

State- and target-isotope-dependent cross sections for electron captur e in collisions of N4+(2s) with H(1s), D(1s), and T(1s) are presented for the energy range 0.01-6000 eV amu(-1). Results are given for captu re via radial coupling into the N(3+)2s3s(1)S, 2s3p(1)P degrees, 2s3d( 1)D, 2s3s(3)S, 2s3p(3)P degrees, 2s3d(3)D, and 2p3s(3)P degrees states and are obtained through a close-coupled, quantum-mechanical, molecul ar-orbital method. Fully ab initio molecular data determined with the spin-coupled valence-bond method are incorporated. Rate coefficients f or temperatures between 1000 and 10(6) K are also presented. Applicati ons to astrophysical environments and laboratory plasmas are addressed . The importance of state-dependent parameters for the modelling of ne bulae emission lines and for fusion plasma impurity diagnostics and th e potential significance of isotope effects to models of the edge regi on of a tokamak device are briefly discussed.
