چکیده

We introduce spin projection methods in the shell model Monte Carlo approach and apply them to calculate the spin distribution of level densities for iron-region nuclei using the complete (pf+g9/2)shell. We compare the calculated distributions with the spin-cutoff model and extract an energydependent moment of inertia. For even-even nuclei and at low excitation energies, we observe a significant suppression of the moment of inertia and odd-even staggering in the spin dependence of level densities.

Nuclear effects in neutrino-nucleus reactions simulated by means of the NUX+FLUKA Monte Carlo generator are compared with the theoretical predictions of the Marteau model. Pion absorption in NUX+FLUKA and non-pionic ∆ decays in the Marteau model differ by about 30%. The fraction of pions produced due to the re-interactions after primary quasi-elastic vertex is in the NUX+FLUKA scheme much highe...

The positivity conditions of the spin density matrix constrain the spin observables of the reaction p̄p → ΛΛ, leading to model-independent, non-trivial inequalities. The formalism is briefly presented and examples of inequalities are provided.
