摘要：

A new experimental technique utilizing a high-spin isomer beam (HSIB) has been developed. The HSIB of Hf-174 was produced by the Be-9(Er-170, 5n)Hf-174 reaction in inverse kinematics, By using the HSIB, the Coulomb excitation of the K-pi = 8(-) isomer in Hf-174 was measured. The gamma-rays from the 9(-) level, which is the first excited state built on the isomer, were observed as well as the cascade gamma-rays of the ground-state rotational band. From the measured gamma-ray yield, a value of 2 +/- 1 e(2)b(2) was extracted for the B(E2 : 8(-) --> 9(-)). This is the first experiment of gamma-ray spectroscopy by means of the HSIB-induced secondary reactions.
