The injection of a neutral beam into the core of magnetically confined plasmas is a foundation for various plasma diagnostics, including charge-exchange recombination spectroscopy, beam emission spectroscopy, and motional Stark effect diagnostics. We review the current status of statistical and nonstatistical collisional-radiative models used for calculation of populations of hydrogen beam excited states. The recently developed collisional-radiative (CR) model in parabolic states, which utilizes collisional data calculated in the Glauber approximation, is discussed in detail. CR simulations with this model show nonstatistical emission for the σ and π components of the HαStark multiplet and provide m-resolved populations. The results of simulations are in excellent agreement with the systematic motional Stark effect (MSE) measurements from the JET tokamak.
