Erste experimentelle Bestimmung einer thermochemischen Größe einer Seaborgiumverbindung

Angewandte Chemie (1999)

Α. Türler W. Brüchle R. Dressler Β. Eichler R. Eichler

Nur wenige Atome von Seaborgium (Sg, Element 106), die zu flüchtigem SgO2Cl2 umgesetzt wurden, reichten aus, um die Sublimationsenthalpie dieser Verbindung gaschromatographisch zu bestimmen. Darüber hinaus wurde gezeigt, daß Sg in der Gruppe 6 eher mit W verwandt ist als mit Mo.

Search for Superheavy Elements in the ^{238}U + ^{238}U Reaction

Physical Review Letters (1980)

H. W. Gäggeler Ν. Trautmann W. Brüchle G. Herrmann Jens Volker Kratz

A search was made for spontaneously fissioning superheavy elements in damped collisions of two uranium nuclei. Different techniques were applied covering the elements 108 to 118 and \ensuremath{\simeq} 126, and a half-life range from 1 ms to more than 1 yr. No evidence for superheavy elements was found at upper cross-section limits of ${10}^{\ensuremath{-}32}$, ${10}^{\ensuremath{-}33}$, and ${10}^{\ensuremath{-}35}$ ${\mathrm{cm}}^{2}$ for half-lives from 1 to 100 ms, 100 ms to 1 d, and 1 d to 1 yr, respectively.

Inclusive measurements of electromagnetic dissociation ofAu197targets

Physical Review C (1993)

T. Aumann J. V. Kratz E. Stiel K. Sümmerer W. Brüchle

Cross sections for the electromagnetic dissociation of $^{197}\mathrm{Au}$ targets by 1.7 GeV/nucleon $^{20}\mathrm{Ne}$ and 1 GeV/nucleon $^{86}\mathrm{Kr}$, $^{197}\mathrm{Au}$, and $^{209}\mathrm{Bi}$ beams have been measured by an activation method. We observe systematic discrepancies between the experimental data and a simple Weizs\"acker-Williams calculation: For the heaviest projectiles, the calculation overpredicts the 1n cross sections, whereas the 2n and 3n cross sections are systematically underpredicted. The deviations can be significantly reduced, however, by calculations including isoscalar and isovector giant quadrupole excitations as well as the possibility to excite multiphonon states. The most important experimental result of the present study is the observation of large cross sections for three-neutron removal from $^{197}\mathrm{Au}$ with $^{197}\mathrm{Au}$ and $^{209}\mathrm{Bi}$ projectiles which can only be explained by a dominant contribution from two-phonon giant dipole excitation. For an almost quantitative reproduction for all xn channels observed, we have to assume a higher excitation probability by roughly a factor of 2 for the double giant dipole resonance as compared to the harmonic approach.

Transfer cross sections from reactions withEs254as a target

Physical Review C (1986)

M. Schädel W. Brüchle Markus Brugger H. W. Gäggeler K. J. Moody

We report radiochemically determined cross sections for the heaviest known actinides produced in transfer reactions of $^{16}$,18O and $^{22}\mathrm{Ne}$ with $^{254}\mathrm{Es}$ as a target. A comparison with data for similar transfers from $^{248}\mathrm{Cm}$ targets is made. Transfer cross sections are extrapolated for the production of the unknown, neutron-rich isotopes of elements 101 through 105, and the unique potential of $^{254}\mathrm{Es}$ as a target to make these exotic nuclei accessible is demonstrated.
