Abstract
The in-beam spectroscopy on N = 91 isotones has been carried out using the C-12 + Nd-150 reaction. The vi(13/2) and vh(11/2) bands of Sm-153 have been extended up to 33/2(+) and 31/2(-), respectively. Two new gamma -rays have been located on the top of the unfavored band with vi(13/2) configuration in Dy-157. Two identical relationships have been established in the low-spi n region of the yrast vi(13/2) configuration between Sm-153 and Gd-155, and between unfavored bands of Gd-155 and Dy-157. Here all these nuclei have t he same neutron number N = 91.
