Giant resonances in Argon isotopes

The isoscalar monopole and quadrupole and isovector dipole giant resonance modes for the nuclei of even-even Argon isotopes 34Ar through 46Ar are calculated. The ground state properties of the nuclei are calculated in the Hartree-Fock approximation with BCS pairing added in a deformed oscillator basis. Then the single particle states are evolved in time using the time dependent Hartree-Fock equations. A time dependant perturbation of the appropriate multi-polarity is added and the strength function of the vibrations is calculated. The form and validity of the resulting giant resonances is discussed.
