摘要：

Low-lying excitations in Te-124 have been investigated using the Sn-122(alpha, 2n) reaction at beam energies of 21 and 23 MeV. Standard in-beam spectroscopy techniques of excitation function, gamma-gamma-coincidence and gamma-ray angular distribution measurements were used. A level scheme up to 3410 keV was constructed. Nine new gamma-rays have been placed and definite spin-parity assignments were made to a number of new levels. Among the new states identified were possible 10+ and 8+ members of the ground-state quasiband. To test proposed collective properties, non-yrast states populated in this work are examined through their relative B(E2) values and mixing ratios. No evidence supporting the existence of strong intruder components has been found.
