Neutron total cross sections of the elements Sc, V, Cu and Rh have been measured for energies 8–500 μeV using the ultracold neutron time-of-flight spectrometer [1] at the Munich research reactor FRM. 1/v-fits to the total cross sections were carri

The parameters a and DELTA for the Fermi gas model with fictive ground state are determined for about 220 nuclei from experimental level densities at low excitation energy and at the neutron binding energy. In agreement with previous results it is fo

Significant discrepancies exist in available data on the slow neutron scattering cross section of vanadium, which has been used as a reference standard in many scattering experiments. We have made an accurate measurement of the vanadium total cross s

Neutron transmission measurements were performed at 18.8 eV neutron energy on F, Al, Sc, V, Fe, Co, Cu, Zn and Nb, in order to acurately determine the "free" scattering cross-sections of these elements. Coherent neutron scattering amplitudes are deri

A precise transmission measurement of the cross sections of Bismuth, Lead, Silicone and Carbon for 130 eV neutrons (Co-resonance) has been carried out. A new resonance method has been applied, using epithermal reactor neutrons, which have been scatte

A method is described to produce beams of monoenergetic neutrons by means of resonance scatterers, placed in the tangential beam tube of a reactor. The method has been studied both experimentally, in measurements with some resonance sources at the Mu

Cross sections for (n, 2n) processes induced by 14.7-MeV neutrons have been measured by activation for nuclei ranging from Ce to Pb. The (n, 2n) cross sections are 10–20% smaller than the total non-elastic cross sections of these nuclei. The data g

The slow neutron absorption cross sections of gold and cobalt have been accurately redetermined by transmission measurements in the neutron wavelength range 4 to 47 A. For the range 4 to 7.6 A a new time-of-flight spectrometer at the FRM reactor was

New measurements of the n-d coherent scattering amplitude and epithermal cross section are reported. The results a coh = 6.672±0.007 fm, σ free = 3.390±0.012 b, are inconsistent with the scattering lengths, proposed by Van Oers and Seagrave. From
