“…Owing to the close proportionality in both ( 3 He, t) and (p, p ′ ) reactions, it is expected that the analog GT and spin-M 1 states are excited with corresponding strengths. In (p, p ′ ) measurements, it is reported that the J π = 1 + spin-M 1 states in the even-even pf -shell nuclei are observed in the E x = 7 − 14 MeV region [61][62][63]. Furthermore, by comparing the (p, p ′ ) and ( 3 He, t) spectra measured at 0 • , corresponding states, i.e., isospin analog states, populated in M 1 σ and GT transitions starting from T z = +1 pf -shell nuclei 58 Ni and 54 Fe have been studied in detail for the 58 Ni and 58 Cu pair and the 54 Fe and 54 Co pair, respectively [20,21].…”

ROTATIONAL-INVARIANT MODEL OF THE STATES WITH Kπ=1+ AND THEIR CONTRIBUTION TO THE SCISSORS MODE

“…The orbital mode 1 + states has been found for the isotopes with permanent deformation in a wide region beginning from light nuclei (such as 46 Ti) up to the actinides, including also transitional and γ-soft nuclei. [6][7][8][9][10][11][12][13] The remarkable features of the scissors mode obtained from experimental results are the quadratic dependence of the summed B(M1) values on the ground state deformation parameter δ and the strong fragmentation of the M1 strength above the pairing gap up to 4 MeV excitation energy. [14][15][16] There exists a strong correlation between the B(E2, 0 + 1 → 2 + 1 0) strength and summed B(M1) strengths and saturation of these strengths at midshell.…”
