Title: Structure of odd- A Pt isotopes along the line of stability

Abstract

The structure of the odd-A isotopes 193,195,197Pt, which lie along the line of stability, has been studied up to high spin through multinucleon transfer reactions. Positive- and negative-parity sequences in Pt- 193,195Pt have been considerably extended and multiple band crossings established. An isomer with T 1/2 = 5.0(5) ns and I π = 25/2 - is present in 195Pt. Additionally, the isotopes 193,195Pt are characterized by moderate oblate deformation, and angular momentum generation at high spin in the yrast, positive-parity sequences is attributed to the rotation alignment of i 13/2 neutrons and h 11/2 protons. Lastly, a detailed understanding of the observed features is presented using calculations based on tilted axis cranking covariant density functional theory as well as others with the ULTIMATE CRANKER code.
