Two-neutron knockout reactions from nuclei in the proximity of the proton dripline have been studied using intermediate-energy beams of neutron-deficient {sup 34}Ar, {sup 30}S, and {sup 26}Si. The inclusive cross sections, and also the partial cross sections for the population of individual bound final states of the {sup 32}Ar, {sup 28}S and {sup 24}Si knockout residues, have been determined using the combination of particle and {gamma}-ray spectroscopy. Similar to the two-proton knockout mechanism on the neutron-rich side of the nuclear chart, these two-neutron removal reactions from already neutron-deficient nuclei are also shown to be consistent with a direct reaction mechanism.
