A 1612 MHz search for OH/IR stars near the galactic center was carried out with the 100 m telescope in Effelsberg. The survey covers a 2.5-deg wide strip along the galactic equator between l equals 358 deg and l equals 15 deg. This paper briefly discusses the distribution in galactic coordinates and radial velocity of the strongest sources found. The survey covers the tail of the 'disk component' (l greater than 5 deg) known from earlier studies. In addition a strong 'nuclear bulge' is found with a high source density at absolute value of l less than 2 deg. This is especially marked for sources with relatively small peak separations, which indicates either that the star-formation rate near the galactic center has decreased, or that stars with low masses form in relatively large numbers near the galactic center. The present sample shows no evidence for rotation in the nuclear bulge. The radial velocity distribution appears to be broader for the sources with smaller peak separations.
