Summary
Energy levels in theN=29 isotones (51Ti,52V,53Cr,54Mn,55Fe) arising from the coupling of protons in the 1f 7/2 shell and the single neutron in the 2p 3/2 shell are calculated by the use of effective interactions. The required two-body residual interactions are deduced from the experimental spectra of50Ti and56Co. A comparison with available experimental data shows in general good correspondence. However, some low-lying states indicate the mixing of configurations in which the single neutron outside the48Ca core is in the 2p 1/2 and 1f 5/2 orbits.
Riassunto
Sono stati calcolati per il gruppo degli isotoni51Ti,52V,53Cr,54Mn e55Fe i livelli energetici originati dall’accoppiamento del singolo neutrone nello strato 2p 3/2 con i protoni nello strato 1f 7/2. L’effettiva residua interazione protone-protone e neutrone-protone è stata dedotta dagli spettri sperimentali dei nuclei50Ti e56Co. Il confronto dei livelli calcolati con quelli osservati sperimentalmente mostra in generale un soddisfacente accordo. Comunque, per alcuni livelli a basse energie di eccitazione risulta evidente l’interazione, oltre a quella considerata, di altre configurazioni in cui il neutrone al di fuori del core48Ca si trovi nelle orbite 2p 1/2 e 1f 5/2.
