Query: Unveiling shape resonances in H + HF collisions at cold energies   Resonances are associated with the trapping of an intermolecular complex, and
are characterized by a series of quantum numbers such as the total angular
momentum and the parity, representative of a specific partial wave. Here we
show how at cold temperatures the rotational quenching of HF(j=1,2) with H is
strongly influenced by the presence of manifolds of resonances arising from the
combination of a single value of the orbital angular momentum with different
total angular momentum values. These resonances give rise up to a two-fold
increase in the thermal rate coefficient at the low temperatures characteristic
of the interstellar medium. Our results show that by selecting the relative
geometry of the reactants by alignment of the HF rotational angular momentum,
it is possible to decompose the resonance peak, disentangling the contribution
of different total angular momenta to the resonance.
