The channeling effect of low energy ions along the crystallographic axes and planes of NaI(Tl) crystals is discussed in the framework of corollary investigations on WIMP dark matter candidates. In fact, the modeling of this existing effect implies a more complex evaluation of the luminosity yield for low energy recoiling Na and I ions. In the present paper related phenomenological arguments are developed and possible implications are discussed at some extent.

- Global interpretation of direct Dark Matter searches after CDMS-II results (2009, methodology): “The fraction of recoil nuclei for which this happens has been calculated in [43], but this calculation leaves room for some debate [14, 44, 45], since the channeling effect has not been measured in the relevant energy range so far.”
- Dark matter direct detection with non-Maxwellian velocity structure (2009, background): “The current iteration of LDM involves “channelling” [75, 50] whereby for some small fraction of the time the entirety of the nuclear recoil energy is converted to scintillation light.”
- Dark Matter Candidates from Particle Physics and Methods of Detection (2010, background): “More recently, astrophysics (81) and channeling (82; 83), a condensed matter effect that effectively lowers the threshold for crystalline detectors, have been proposed as possible remedies to allow elastic scattering to explain DAMA without violating other constraints.”
- Spin-independent elastic WIMP scattering and the DAMA annual modulation signal (2008, methodology): “In the analysis of DAMA data the effects of quenching and channeling are important [21, 38].”
