Abstract

A high galactic latitude (‖b‖ > 10°, δ >- −30°) sample of 175 IRAS sources located within the core of molecular clouds has been searched for H2O maser emission with the Medicina 32 m dish operated at 22 GHz . 17% of the sample previously searched by other authors contained only 4 detection. The search did not produce any new water maser emitter, while the previously known maser were seen again. The low value of 2% overall detection rate can be explained in terms of galactic distribution of massive cores.
