Abstract

The escape rate of nitrogen from Mars is calculated to be 2.3×10 ⁵ s ⁻¹ for low solar flux conditions and 8.9×10 ⁵ s ⁻¹ for high solar flux conditions. The major source of energetic atoms is dissociative recombination of ground state and vibrationally excited N ₂ ⁺ ions. The measured ¹⁵ N/ ¹⁴ N isotope ratio can be reproduced by postulating an early dense atmosphere during which little differentiation occurred.
