The odd-odd 54,56,58,60,62,64 Mn isotopes (Z = 25) were studied using bunched-beam collinear laser spectroscopy at ISOLDE, CERN. From the measured hyperfine spectra the spins and magnetic moments of Mn isotopes up to N = 39 were extracted. The previous tentative ground state spin assignments of 58,60,62,64 Mn are now firmly determined to be I = 1 along with an I = 4 assignment for the isomeric states in 58,60,62 Mn. The I = 1 magnetic moments show a decreasing trend with increasing neutron number while the I = 4 moments remain quite constant between N = 33 and N = 37. The results are compared to large-scale shell-model calculations using the GXPF1A and LNPS effective interactions. The excellent agreement of the ground state moments with the predictions from the LNPS calculations illustrates the need for an increasing amount of proton excitations across Z = 28 and neutron excitations across N = 40 in the ground state wave functions from N = 37 onwards.

Abstract. With the recent advances in radioactive ion beam technology, Coulomb excitation at safe energies becomes an important experimental tool in nuclear-structure physics. The usefulness of the technique to extract key information on the electromagnetic properties of nuclei has been demonstrated since the 1960's with stable beam and target combinations. New challenges present themselves when studying exotic nuclei with this technique, including dealing with low statistics or number of data points, absolute and relative normalisation of the measured cross sections and a lack of complementary experimental data, such as excited-state lifetimes and branching ratios. This paper addresses some of these common issues and presents analysis techniques to extract transition strengths and quadrupole moments utilising the least-squares fit code, gosia.

“…This situation in 58 Sc is significantly different from the isotones 60 V and 62 Mn [5] where decays proceed via E 2 (and M1) transitions. In 62 Mn, a 4 + β-decaying isomer at 346 keV has been proposed [21,22]. Also in the less neutron-rich Sc isotopes experimental results on isomeric and β decays suggest positive parity for the γ -and β-decaying isomers of 54,56 Sc as well [23].…”
