A STUDY OF RADIATIONS FROM W$sup 18$$sup 7$
ABS>The decay of 24-hr W/sup 187/ was studied using a six-gap beta spectrometer, a single-gap beta spectrometer, scintillation spectrometers, electron-gamma, and gamma-gamma coincidence techniques. Beta transitions having end-point energies of 1329 plus or minus 5 (18), 625 plus or minus 10 (74), and 325 plus or minus 20 kev (8%) are found. The high-energy group corresponds to a first-forbidden trsnsition, the second one to an allowed or first-forbidden transition. Unreported lines belonging to known transitions are measured. Intensities are given for 3 Auger electron groups and for 45 internal conversion electron groups assigned to 15 radiative transitions including a 36-kev transition not previously established. Multipole orders are found according to conversion ratios and absolute conversion coefficients. The Li/sup I/:L/sub II/L/ sub III/ conversion electron ratios for the 72-kev delayed El transition are normal. (auth)
