We have studied in [sup 164]Dy the double-γ excitation with cold neutron capture. Using the GRID method, the 4[sup +] state at 2173 keV was found before to exhibit the decay pattern required for a double-γ vibration. During the analysis of the lifetime measurement several errors have been found in the level scheme. A new study of this nucleus by cold neutron capture at PSI was started. A first experiment of γ-γ coincidence has been performed at the new PGA installation at SINQ and confirms our earlier work. At the same time, we have searched for the 0[sub γγ][sup +] excitation but no such state was observed. © 2000 American Institute of Physics.

    The dependence of the ultracold neutron capture cross section in targets with a thickness smaller than the neutron wavelength is calculated in the time-dependent quantum theory. It is shown that, for low velocities of neutrons, their capture cross section s[sub c]~v, i.e., tends to zero as the...

    The Krypton isotopes lie in one of the most sensitive, complicated and, therefore, interesting region of the s-process nucleosynthesis. This mass region, in fact, receives substantial contribution from both the weak and the main component of the s-process. In addition to that, the branching in...
