英文摘要	High-spin states in Re-169 have been investigated by means of in-beam gamma-ray spectroscopy techniques with the Sm-144(Si-28, 1p2ngamma)Re-169 reaction. X-gamma and gamma-gamma-t coincidences, gamma-ray anisotropies, and DCO ratios were measured. A strongly coupled band based on the 9/2(-) [514] Nilsson state and a decoupled band built on the h(9/2) intruder proton orbital (nominally 1/2(-) [541]) have been established. The AB neutron crossings are observed at (h) over bar omega = 0.23 and 0.27 MeV for the 9/2-[514] and 1/2-[541] bands, respectively. The 9/2-[514] band in Re-169 shows the largest signature splitting at low spin among the odd-mass Re isotopes. Band properties of the AB neutron crossing frequencies, alignment gains, and signature splittings are discussed, and compared with those in the heavier odd-A Re isotopes. Additionally, a three-quasipariticle band is observed, and the pi9/2(-) [514] x nuAE configuration is proposed tentatively.
