| Abstract: | Attempts at the Lawrence Berkeley Laboratory to produce superheavy elements (SHE) by using the reactions of ⁴⁸Ca with ²⁴⁸Cm and ¹³⁶Xe with ²³⁸U have been unsuccessful. These negative results led researchers to consider the possibility that these reactions (and their associated mechanisms) do not lead to the formation of superheavy nuclei with sufficiently low excitation energies. Consequently, the number of surviving atoms of superheavy elements is well below detection thresholds, even for relatively low estimates for prompt fission losses. A summary of some new experimental evidence supporting the above hypothesis is presented, and possible alternative heavy-ion--heavy-target combinations are suggested for SHE synthesis. 10 figures, 1 table, 43 references. |
