Abstract. The π− + 2H → n + n, π− + 3H → n + n + n, π− + 3He → n + d and π− + 3He → p + n + n capture reactions from the lowest atomic orbitals are investigated under full inclusion of final state interactions and employing the single-nucleon and two-nucleon transition operators derived at leading order in chiral effective field theory.
