The calculation of the spreading width of a compound nuclear reaction caused by a symmetry breaking $K$-body force acting in an $A$-body system ($K << A$, usually $K=2$) involves the determination of the local average square matrix element in $A$-bod

We derive a compact formula for the mean squared matrix element of a two-body force in the A -body space and its N -exciton subspaces. Application to the spreading widths of symmetry breaking interactions shows that the contributions of rank one and

An analytical model for statistical multistep direct and multistep compound reactions is presented. It predicts emission spectra for neutrons, protons, alphas, and photons including equilibrium, preequilibrium, direct (collective and non-collective)

Excitation functions were measured for the {sup 49,50}Ti({ital n},{ital p}){sup 49,50}Sc reactions from threshold to 10.5 MeV. Use was made of the activation technique in combination with high-resolution {gamma}-ray spectroscopy and anticoincidence {

A unique description of (n, p) and (n, 2n) activation cross sections as well as emission spectra is proposed within a pure multistep approach. Calculations are presented for 8 nuclei (A=47 ... 65) in the incident energy range from zero up to 20 MeV.

In the dilute gas approximation closed-form expressions are derived for (i) the propagation of k-body forces from k-to N-particle space and (ii) transition strengths between different spaces (N≠N′). They are presented in their local and global-av

The fermentation of olives is usually carried out spontaneously by natural microbiota. Spontaneous fermentation has some disadvantages, such as the formation of defects in the end product due to the activities of undesirable microorganisms. The use o

A unique description of emission spectra, angular distributions and activation cross sections is proposed within a pure statistical multistep approach. The analytical model is based on both many-body theory (by Green’s function formalism) and rando
