Nuclear matter compressibility from isoscalar giant monopole resonance.
We examine the status of the nuclear matter compressibility K„obtained from experimental data of the strength distribution of the giant monopole resonance in nuclei and employing a least-squares fit to a semiempirical expansion of the nucleus compressibility E~ in A ' '. We present arguments indicating that all the coefficients of this expansion must be determined by a fit to the data. In our a...
متن کاملCharged-particle decay at finite temperature
Radiative corrections to the decay rate of charged fermions caused by the presence of a thermal bath of photons are calculated in the limit when temperatures are below the masses of all charged particles involved. The cancellation of finite-temperature infrared divergences in the decay rate is described in detail. Temperature-dependent radiative corrections to a two-body decay of a hypothetical...
متن کاملStructure and direct decay of Giant Monopole Resonances
We study structure and direct decay of the Giant Monopole Resonance (GMR) at the Random Phase Approximation (RPA) level using the time-dependent energy density functional method in the linear response regime in a few doubly magic nuclei. A proper treatment of the continuum, through the use of large coordinate space, allows for a separation between the nucleus and its emitted nucleons. The micro...
متن کاملGiant Monopole Resonance and Nuclear Compression Modulus For
Using a collective potential derived on the basis of the Generator Coordinate Method with Skyrme interactions we obtain values for the compression modulus of 40Ca which are in good agreement with a recently obtained experimental value. Calculated values for the compression modulus for 16O are also given. The procedure involved in the derivation of the collective potential is briefly reviewed an...
متن کاملProperties of the Overtone of the Isoscalar Giant Monopole Resonance
A semi-microscopic approach, based on the continuum-random-phase Approximation (CRPA) method, is applied to describe the main properties (strength function, transition density, direct-nucleon-decay branching ratios) of the overtone of the isoscalar giant monopole resonance. Results of the calculation are presented for 208Pb in comparison with those obtained for the isoscalar monopole and dipole...
