have been performed on natural samples of Pd; Ru, Mo<br />
and Hf. For Pd, Ru and Mo capture gamma-ray spectra<br />
have been observed to select the resonances due to<br />
odd nuclei. The resonance peaks in time-of-flight<br />
spectra of singles and coincidences have been analysed<br />
by measuring their integral or partial areas. In the<br />
more complicated case of Hf, the known parameters have<br />
been used to obtain with a best fit procedure the relative<br />
strength of the resonances. To this end our<br />
shape analysis program has been modified to take into<br />
account multiple scattering effects. The spin could<br />

be assigned to 50 resonances of Pd, $6 resonances<br />
of 99 ,101 Ru, 24 resonances of °5>97Mo and 45 reso_<br />
177<br />
nances of "Hf. The assignments are listed in the<br />
following tables (I, II, III, IV).<br />

Several calculations have been performed on the kinematics<br />
of nuclear reactions, especially for the production<br />
of monoenergetic neutrons T18] and of the<br />
non-relativistic T19] and relativistic T20] parameters<br />
of nuclear reactions.<br />
2.9.2. Instrumentation of Analog Signals and Analog-to-Digital<br />
Conversions; Pulse Height Converter<br />
H. Yerelst, H. Meyer<br />
A servostabilized pulse height converter of great linearity,<br />
stability and speed, especially useful for<br />
precision •y- s P ec 't ;:i: ' osco Py with germanium detectors was<br />
developed. Because of the analog controlled sliding<br />
energy window foreseen, the system allows to measure<br />
also high energy -^-spectra with high resolution, if<br />
small memories are used for storage. In such a case
