✦ Synopsis


Mass, isotopic yields and single-fragment kinetic energy measurements for thermal-neutron induced fission of 245 Cm at the Lohengrin fission-product mass separator are described. Using an ionization chamber coupled to the mass separator, we have measured the mass and isotopic yields from fragment mass A = 67 up to A = 77 over three yield decades. This considerably extends the data set previously known for the light peak. A full set of data is now available for this actinide in the super-asymmetric mass region. The results of mass and isotopic yields are compared with those of other compound nuclei to highlight the shell effect at mass 70 for the 246 Cm compound-nucleus system. Also, the present results are compared to the data from the European library JEF2 and the evaluation from Wahl's Z p model.
