Abstract

Recent measurements of the ⁵⁴Fe(p, γ)⁵⁵Co cross section indicate the existence of a splitting between the T_< and T _> components of the giant dipole resonance. We have calculated the (p, γ) cross section in the shell-model formalism. The bound-state interaction was determined by a fit to fp and sd shell nuclei. The calculation predicts the isospin splitting of ≈ 2.4 MeV and is consistent with all data in the energy region E_p = 9–15 MeV as well as the low-lying ⁵⁵Co spectrum.

Strangeness exchange reactions with the recoil corrected continuum shell model
1986, Nuclear Physics, Section A
The procedure for calculating strangeness exchange cross sections in the recoil corrected continuum shell model formalism is developed. Cross sections are compared with existing ¹²_ΛC, ¹⁶_ΛO and ⁴⁰_ΛCa data and agreement is good. The calculated ¹⁶_ΛO, 4° spectrum demonstrated the ability of the RCCSM to calculated bound states, resonances, and quasi-free scattering in one formalism. A search for collective states was performed. After proper removal of center-of-mass excitations, no substantial collectivity was found. A survey of stretched excitations was performed. The ¹⁶_ΛO(3⁺) and ²⁸_ΛSi(5⁺) states were found to be narrow and contain more than 85% of the 1p_Λ 1h_n strength. They are therefore, good candidates for initial (γ, K⁺) studies. In contrast, only 50% of the 1p_Λ 1h_n strength for ¹²_ΛC(3⁺) will be observed in one state, with the remaining strength spread over several MeV with weak structure.
