1994Be24, 1998Do08, 2006KeZZ: 135Sn from Pb(238U,F), E=750 MeV/nucleon, fragment separator; identification by Bρ-ΔE-tof techniques
2005Sh36, 2005Sh23, 2002Sh08 (also 2005Sh53,2001Sh12): 135Sn produced by high-energy neutron fission of UC2 target at ISOLDE/ CERN facility. The high-energy neutrons were produced by bombarding a tungsten rod (adjacent to the UC2 target) with 1.4 GeV protons. The Sn ions were extracted and mass separated. The β- and delayed neutron decay of 135Sn were studied by β and γ spectroscopy.
2005Ko40, 2001Ko45: 135Sn produced by thermal neutron fission of 235U followed by mass separation at OSIRIS mass separator facility in Studsvik.
2015Lo04: 135Sn nuclide produced at RIBF-RIKEN facility in 9Be(238U,F) reaction at E=345 MeV/nucleon with an average intensity of 6×1010 ions/s. Identification of 135Sn was made by determining atomic Z and mass-to-charge ratio α/Q, where Q=charge state of the ions. The selectivity of ions was based on magnetic rigidity, time-of-flight and energy loss. The separated nuclei were implanted at a rate of 50 ions/s in a stack of eight double-sided silicon-strip detector (WAS3ABi), surrounded by EURICA array of 84 HPGe detectors. Correlations were recorded between the implanted ions and β rays. The half-life of 135Sn isotope was measured from the correlated ion-β decay curves and maximum likelihood analysis technique as described in 2014Xu07. Comparison of measured half-lives with FRDM+QRPA, KTUY+GT2 and DF3+CQRPA theoretical calculations
2013Va12, 2012Ha25: measured mass excess by tof ion cyclotron resonance technique
2002Ur04 predict following yrast levels from systematics of n=85 isotones: 7/2- g.s.; 5/2- at 200; 3/2- at 400; 9/2- at 700; 11/2- at 800 and 15/2- at 1200. These predictions are compared by 2002Ur04 with OXBASH model calculations.
