Abstract
The cross sections for the production of evaporation particles have be en measured in the neutron-evaporation and charged-particle-evaporatio n channels of P-31 + Ta-181 and Cl-35 + Lu-175 interactions. These mea surements have been performed at excitation energies of compound nucle i between 50 and 90 MeV. These data are compared with the cross sectio ns computed on the basis of the standard statistical model of compound -nucleus deexcitation and with the cross sections for the production o f these evaporation products in cold-fusion reactions. Some general re gularities in the behavior of the hindrance factors for cold-fusion re actions are discussed. The branching ratios of ex decay have been meas ured for Rn-203m, At-198m,At-g, At-200,At- 201,At- 203, and (198)po is otopes.
