on <strong>the</strong> incident particle kinetic energy and<br />

nucleonic composition <strong>of</strong> <strong>the</strong> fissioning systems.<br />

Characteristic regularities were revealed in<br />

<strong>the</strong> behaviour <strong>of</strong> <strong>the</strong> fission modes, and <strong>the</strong>se<br />

phenomena were used to develop new systematics<br />

<strong>for</strong> <strong>the</strong> pre- and post-neutron emission fragment<br />

mass yields from Th to Bk target nuclei in reactions<br />

with protons and neutrons at kinetic energies<br />

ranging from 5 to 200 MeV. These systematics have<br />

been used to <strong>for</strong>mulate <strong>the</strong> PYF computer code.<br />

This approach reproduces <strong>the</strong> main features <strong>of</strong> <strong>the</strong><br />

experimental data and can be used as a basis <strong>for</strong> <strong>the</strong><br />

calculation <strong>of</strong> fission product yields in reactions<br />

with neutrons over <strong>the</strong> energy range 5–200 MeV <strong>of</strong><br />

interest <strong>for</strong> <strong>the</strong> transmutation <strong>of</strong> minor actinides.<br />
