State- and isotope-dependent charge transfer of N4+ with atomic hydrogen in astrophysical and fusion plasmas

State- and target-isotope-dependent cross sections for electron capture 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 capture 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, molecular-orbital method. Fully ab initio molecular data determined with the spin-coupled valence-bond method are incorporated. Rate coefficients for temperatures between 1000 and 10(6) K are also presented. Applications to astrophysical environments and laboratory plasmas are addressed. The importance of state-dependent parameters for the modelling of nebulae emission lines and for fusion plasma impurity diagnostics and the potential significance of isotope effects to models of the edge region of a tokamak device are briefly discussed.
