“…Apart from the 7.1 ns isomer discussed above, three other 48 K transitions of 143-, 279-and 449-keV were sufficiently strong to measure lifetimes. For this purpose, the data from yet another experiment carried out with the plunger technique [23,24] at the PRISMA-CLARA spectrometer were used. In this experiment, the 310-MeV 48 Ca beam was used on a 1.0 mg/cm 2 enriched 208 Pb target evaporated onto a 1.0 mg/cm 2 Ta support.…”

Excited states in the Z = 19, N = 29 neutron-rich 48 K isotope have been studied using deepinelastic transfer reactions with a thick target at Gammasphere and with a thin target at the PRISMA-CLARA spectrometer. The lowest excited states were located; they involve a proton hole in the s 1/2 or d 3/2 orbital coupled to a p 3/2 neutron. A new 7.1(5) ns, 5 + isomer, analog of the 7/2 − isomer in 47 K, was identified. Based on the observed γ-decay pattern of the isomer a revised spin-parity assignment of 1 − is proposed for the ground state of 48 K.

“…This may lead to events with a transition of 107 keV energy being properly correlated with 45 Cr ions but with times related to γ radiation from subsequently implanted ions being processed in the same electronics module. The lower limit of T 1/2 > 80 µs for the isomer in 45 Cr is thus derived from ion-γ correlations occuring within the first 80 µs after implantation or trigger signal, respectively. 45 Sc is the stable mirror nucleus of 45 Cr.…”

“…The lower limit of T 1/2 > 80 µs for the isomer in 45 Cr is thus derived from ion-γ correlations occuring within the first 80 µs after implantation or trigger signal, respectively. 45 Sc is the stable mirror nucleus of 45 Cr. A long-lived, T 1/2 = 318(7) ms, isomeric 3/2 + state is established as low as at E x = 12.4 keV excitation energy above the 7/2 − ground state.…”

“…The second excited state in 45 Sc is known to have I π = 3/2 − at E x = 377 keV with a half-life of T 1/2 = 43.3(23) ps [37]. With these two states being the only ones known in 45 Sc with T 1/2 > 10 ps, and given a reliably measured ground-state spin and parity of I π = 7/2 − for 45 Cr [38], the present new isomeric state in 45 Cr can be associated with either the 3/2 − or 3/2 + mirror state in 45 Sc. Therefore, the present experimental result on 45 Cr is quoted twice in table 1 to allow for a discussion of both options in section 4.…”

“…Detailed polarization effects of nucleons moving in different orbitals outside the 40 Ca core are studied in section 4.2. This approach, which is different from standard shellmodel calculations with a fixed set of effective charges, has been triggered by recent experimental results in heavier pf -shell nuclei [44,45] and introduced in detail in [46]. Section 4.3 provides first results on M 2 mirror isomers using a restricted sdpf model space [47].…”

Abstract. The revival of transfer reaction studies benefited from the construction of the new generation large solid angle spectrometers, coupled to large γ arrays. The recent results of γ-particle coincident measurements demonstrate a strong interplay between single-particle and collective degrees of freedom that is pertinent to the reaction dynamics. Via transfer of pairs, valuable information on the component responsible for particle correlations has been derived.
