Given the importance of Gamow-Teller (GT) transitions in nuclear structure and astrophysical nuclear processes, we have studied Tz = +3/2 → +1/2, GT transitions starting from the 47 Ti nucleus in the ( 3 He, t) charge-exchange reaction at 0• and at an intermediate incident energy of 140 MeV/nucleon. The experiments were carried out at the Research Center for Nuclear Physics (RCNP), Osaka using the high resolution facility consisting of a high-dispersion beam line and the Grand-Raiden spectrometer. With an energy resolution of 20 keV, individual GT transitions were observed and GT strength was derived for each state populated up to an excitation energy (Ex) of 12.5 MeV. The GT strength was widely distributed from low excitation energy up to 12.5 MeV, where we had to stop the analysis due to the high level density. The distribution of the GT strengths was compared with the results of shell model calculations using the GXPF1 interaction. The calculations could reproduce the experimental GT distributions well. The GT transitions from the ground state of 47 Ti and the M 1 transitions from the isobaric analog state in 47 V to the same low-lying states in 47 V are analogous. It was found that the ratios of GT transition strengths to the ground state, the 0.088 MeV, and the 0.146 MeV states are similar to the ratios of the strengths of the analogous M 1 transitions from the IAS to these states. The measured distribution of the GT strengths was also compared with those starting from the Tz = +3/2 nucleus 41 K to the Tz = +1/2 nucleus 41 Ca.

“…In the T z = +3/2 → +1/2, CE reaction, both the Fermi strength and the GT strength contribute in the transition to the IAS. In order to derive the B(GT) strength in the transitions to the IAS, we introduce the ratio of GT and Fermi unit cross-sections denoted as R 2 [7] and defined by…”

“…There is a simple proportionality between the cross sections at linear momentum transfer q=0 of these reactions and the B(GT) values [3]. GT transitions can be accessed by CE reactions without the Q-value limitation of β decay, and B(GT) values can be determined if a standard B(GT) value is known from a β-decay study.…”

A high energy-resolution 9 Be( 3 He,t) 9 B charge-exchange reaction was performed around a scattering angle of 0• and at an intermediate incident energy of 140 MeV/nucleon for the study of precise Gamow-Teller (GT) transition strengths. The energy resolution of 30 keV allowed a precise deconvolution of the spectrum and the determination of angular distributions of cross-sections, excitation energies and decay widths. The GT strength of 10 states has been determined for the first time using the GT strength of the analogous β decays of 9 Li and 9 C as standards. The large difference between the GT strengths going to the low-lying T =1/2 and the highly excited T =3/2 states is interpreted as a result of their different spatial structures. The obtained GT strength distribution is compared to the results of a (p,n) experiment with lower resolution performed in the 1980s. In particular, the width of the 16.8 MeV, J π =(5/2 + ) state has been determined for the first time.
