The direct search for dark matter in the form of weakly interacting massive particles (WIMP) is performed by detecting nuclear recoils produced in a target material from the WIMP elastic scattering. The experimental identifi- cation of the direction of the WIMP-induced nuclear recoils is a crucial asset in this field, as it enables unmistakable mod- ulation signatures for dark matter. The Recoil Directional- ity (ReD) experiment was designed to probe for such direc- tional sensitivity in argon dual-phase time projection cham- bers (TPC), that are widely considered for current and future direct dark matter searches. The TPC of ReD was irradi- ated with neutrons at the INFN Laboratori Nazionali del Sud. Data were taken with nuclear recoils of known directions and kinetic energy of 72 keV, which is within the range of interest for WIMP-induced signals in argon. The direction-dependent liquid argon charge recombination model by Cataudella et al. was adopted and a likelihood statistical analysis was per- formed, which gave no indications of significant dependence of the detector response to the recoil direction. The aspect ratio R of the initial ionization cloud is R < 1.072 with 90 % confidence level
