Neutrino–nuclear responses associated with astro-neutrinos, single beta decays and double
beta decays are crucial in studies of neutrino properties of interest for astro-particle physics …

The usual neutron-proton BCS wave function is simultaneously projected on both the good
neutron and proton numbers using a discrete projection operator. The projected energy of …

Particle-number fluctuations effects on the beta transition probabilities are studied in the
neutron–proton pairing framework. The Hamiltonian of the system has been considered in …

The effect of the particle-number symmetry restoration on the root mean square (rms) proton
and neutron radii of neutron-deficient nuclei is studied in the isovector pairing case. As a first …

The physical properties of the nuclear shape have been investigated through the charge
square radius () and the quadrupole (Q2) and hexadecapole (Q4) moments of the even …

Expressions of the spectroscopic factors (SFs) corresponding to one-particle transfer
reactions have been established using a schematic definition. These expressions have …

An expression of the number-projected electric quadrupole moment Q2 has been
established in the isovector pairing case using the SBCS discrete projection before variation …

The influence of the isovector neutron–proton (np) pairing effect on nuclear statistical
quantities is studied in N≈ Z even–even systems. Expressions of the energy, the entropy …

An extended Holstein-Primakoff mapping which incorporates both single-and double-
fermion mappings is used in the context of thermofield dynamics to study the next-to-leading …

The validity of the so-called fully renormalized quasiparticle random phase approximation is
tested, under schematic model conditions. It is shown that this approximation does not fulfill …
