             abstract = "Different studies show that dark matter of non-baryonic origin 
                         might exist. There is experimental evidence that at least one form 
                         of dark matter has been detected through microlensing effects. 
                         This form of dark matter is named MACHOs (massive astrophysical 
                         compact halo objects). The MACHO collaboration estimated that the 
                         masses of these objects are to be in the range 0.15–0.95M_, where 
                         the most probable mass is of 0.5M_. Some authors argue that MACHOs 
                         could be black holes, and that they could form binary systems, 
                         BHMACHO binaries. As is well known, binary systems are sources of 
                         gravitational waves. The Brazilian spherical antenna will operate 
                         in the frequency band of 3.0–3.4 kHz, sensitive to binaries of a 
                         pair of 0.5M_ black holes just before coalescing. In the present 
                         work we study the detectability of these putative BHMACHO binaries
