The cross sections for p- + (Hμ-)1s (H = p, d, t) are calculated in the hyperspherical close-coupling method for collision energies below the (Hp-)n=4 threshold. The results show good convergence with respect to basis size. The formation cross section of (Hp-)n=2 is dominant and two orders of magnitude larger than that of (Hp-)n=1 below the (Hp-)n=3 threshold, while the (Hp-)n=3 formation cross-section exceeds that for (Hp-)n=2 formation above the (Hp-)n=3 threshold. Resonance parameters are also calculated below thresholds of (Hp-)n=2-4.
