“…It should be mentioned here that the renormalization proposed by van Egmond and Allaart [19] has similar aspects to the present one. They have included various correlations induced through a nearly realistic shell-model hamiltonian.…”

“…A significant difference from Ref. [19], as well as from other studies, is that the 56 Ni-core excitation plays a certain role in the present case, which may be characteristic to the present mass region.…”

“…In this sense, a part of the H 2 CM effect has been taken into account in Ref. [19]. The H n CM exploited in the present work, on the other hand, provides us with a systematic way to pick up important bases.…”

“…A semi-realistic interaction with the single-range Yukawa form has been applied to investigate several of the IBM-2 parameters in Ref. [19]. On the other hand, this is the first work to derive IBM-2 hamiltonian from a realistic shell-model interaction; the Kuo-Brown interaction, in the present case.…”

We present a new method by which wavefunctions with simple structure are renormalized so as to contain more complicated structure. This method, called H n -cooling method, is applied to the study of the quadrupole collective motion of 56 Fe, 54 Cr, 58 Fe and 56 Cr. The shell-model wavefunctions of lowestlying states of these nuclei are well treated by this method. By using the wavefunctions obtained via the H n -cooling method, IBM-2 parameters are derived from a realistic shell-model hamiltonian and transition operators. The Majorana interaction becomes sizably repulsive, primarily as an effect of the renormalization. The bosonic E2 effective-charges are enhanced due to the renormalization, while a quenching occurs in the M 1 and M 3 parameters for proton bosons. It is shown that the χ parameters take similar values in the 1 hamiltonian and in the E2 operator.
