Measurement of emission probabilities for principal gamma-rays of Gd-159 wi
th 4 pi beta (ppc)-gamma (HPGe) coincidence apparatus has given precise val
ues as indicated by uncertainties of about 1%. Improved certainties are see
n when comparing the present results with emission probabilities evaluated
in Nuclear Data Sheets (Helmer, 1994, p. 72) for which the uncertainties ar
e about 24%. The improvement resulted in precise decay scheme parameters of
the nuclide. (C) 2001 Elsevier Science Ltd. All rights reserved.
