Polarized negative muons were used to study the dynamics of non-equilibrium charge carriers in diamond. From the behavior of the muon polarization it is concluded that the acceptor center _μB in diamond is formed in the diamagnetic state (with the probability close to unity) and then, by capturing a hole, turns to the paramagnetic state. The hole capture rate by an ionized acceptor center _μB^- in synthetic diamond was found to depend on temperature as 1/T^α, where α=(1.5-2.5) at T>80 K.
