The Isoscalar Giant Monopole Resonance (ISGMR), often referred to as the nuclear "breathing mode," provides essential constraints on the incompressibility of nuclear matter and therefore on the nuclear equation of state. In this contribution, recent investigations of the ISGMR strength distribution and its fine structure obtained through high-resolution inelastic scattering measurements will...
It has been established that inelastic alpha scattering at a few hundreds MeV, particularly at very forward scattering angles including 0◦, is effective for probing the Isoscalar Giant Monopole Resonance (ISGMR) strength distribution (E0) in atomic nuclei. Two previous studies on the evolution of the ISGMR in the even-even 40,42,44,48Ca isotopes were conducted at two different facilities: the...
The NUMEN (NUclear Matrix Elements for Neutrinoless double-beta decay) project aims to obtain the nuclear matrix elements (NME) to be used as inputs in models to determine the lifetime of neutrinoless double-beta ($0\nu\beta\beta$) decay, which is related to the absolute mass of the neutrino [1]. This will be achieved by conducting heavy-ion double charge-exchange (DCE) reactions and measuring...
The search for neutrinoless double beta (0νββ) decay provides a unique probe of the Majorana nature of neutrinos, i.e whether neutrinos are their own antiparticles. The observation of this process would imply the violation of lepton number conservation and signal new physics, beyond the Standard Model. However, the interpretation of 0νββ experimental searches relies critically on nuclear...
Coincidence counting techniques are widely used to determine correlated γ-ray emissions from nuclear decays. Measured singles and coincidence rates share common factors - i.e. absolute efficiency - that can be divided out in analysis. However, standard formulations often assume perfect isotropic correlation between emitted quanta, neglecting possible decay chain losses, and ignore angular...
