Abstract
The excitation functions of the short-lived tungsten isotopes W-164 an d W-165 produced in the nuclear reaction Mg-24 + Sm-144 were measured for E-Lab = 109 MeV-141 MeV. Two gamma-lines at (187.0 +/- 0.1) keV an d (268.7 +/- 0.2) keV were discovered in the gamma-spectra of the tung sten fraction after chemical separation at a beam energy of 128 MeV wh ich we assign to W-164. The half-life of the 187.0 keV gamma-line is ( 7.0 +/- 0.2) s.
