The incompressibility of infinite nuclear matter (đŸâ) is a parameter in the description equation state that governs energy cost associated with density oscillations near saturation density. most direct experimental method for studying this property to probe isoscalar giant monopole resonance (ISGMR) finite nuclei.

A consistent folding model analysis of the ($\ensuremath{\Delta}S=0,\ensuremath{\Delta}T=1$) charge exchange $(p,n)$ reaction measured with $^{48}\mathrm{Ca}$, $^{90}\mathrm{Zr}$, $^{120}\mathrm{Sn}$, and $^{208}\mathrm{Pb}$ targets at proton energies 35 45 MeV is done within a two-channel coupling formalism. The nuclear ground state densities given by Hartree-Fock-Bogoliubov formalism density-dependent CDM3Y6 interaction were used as inputs for calculation nucleon optical potential form...
Analyses of the inelastic α+12C scattering at medium energies have indicated that strength Hoyle state (the isoscalar 02+ excitation 7.65 MeV in 12C) seems to exhaust only 7â9% monopole energy weighted sum rule (EWSR), compared about 15% EWSR extracted from electron data. The full transition predicted by realistic microscopic α-cluster models can be shown up 22% EWSR. To explore missing scattering, we performed a fully folding model analysis Elab=104â240MeV using 3-α resonating group wave...
The nuclear mean-field potential built up by the $^{12}\mathrm{C}+^{12}\mathrm{C}$ interaction at energies relevant for carbon burning process is calculated in double-folding model (DFM) using realistic ground-state density of $^{12}\mathrm{C}$ and CDM3Y3 dependent nucleon-nucleon (NN) interaction, with rearrangement term properly included. To validate use a NN DFM calculation low-energy regime, an adiabatic approximation suggested nucleus-nucleus overlap density. reliability predicted this...
The complex optical potential and inelastic form factor given by the folding model for $\alpha+^{12}$C scattering are used to calculate ($\alpha,\alpha'$) cross sections known isoscalar states of $^{12}$C in an elaborate coupled channel approach. strengths factors these then fine tuned against data deduce corresponding $E\lambda$ transition strengths. A significant $E2$ strength has been obtained $2^+_2$ state from present analysis measured at $E_\alpha=240$ 386 MeV. $0^+_2,\ 3^-_1,\ 0^+_3,$...
Background: Given the established $2\ensuremath{\alpha}$ structure of $^{8}\mathrm{Be}$, a realistic model four interacting $\ensuremath{\alpha}$ clusters must be used to obtain $^{8}\mathrm{Be}+^{8}\mathrm{Be}$ interaction potential. Such four-body problem poses challenge for determination optical potential (OP) that is still unknown due lack elastic scattering data.Purpose: To probe complex in coupled-reaction-channel (CRC) study transfer...

Angular distributions of the elastic and inelastic deuteron-nucleus scattering off $^{24}$Mg, $^{28}$Si, $^{58}$Ni, $^{90}$Zr, $^{116}$Sn, $^{208}$Pb have been measured at a beam energy 98 MeV/nucleon, with goal constraining deuteron optical potential in this kinematical regime, to extract reduced transition probabilities for ground-state transitions low-lying excited states these nuclei. Two models were used analysis $(d,d)$ $(d,d')$ data within model distorted-wave Born approximation:...

An elaborate folding model + coupled channel analysis of the inelastic α+12C scattering has been done using form factors based on nuclear transition densities predicted by antisymmetrized molecular dynamics. The for observed isoscalar states 12C were fine-tuned against measured (α, α') cross sections to estimate corresponding Eλ strengths.

A new finite-range representation of the JLM effective nucleon-nucleon interaction is suggested based on CDM3Y density dependent functional and M3Y-Paris interaction. The dependence has been carefully adjusted at each energy so that nucleon optical potential (OP) given by in Hartree-Fock calculation nuclear matter closely matches OP Brueckner-Hatree-Fock calculation. used double-folding model to calculate for elastic $^{6}$Li,$^{6}$He,$^{12}$C + $^{12}$C scattering different energies.
