Description
Measurements of proton decay properties provide valuable spectroscopic information on the structure of nuclei far from stability. In this presentation, I will report the results of our decay-spectroscopy study about the extremely neutron-deficient Lanthanum isotopes $^{116,117}$La. These nuclei were produced at the Accelerator Laboratory of the University of Jyväskylä by employing fusion-evaporation reactions, using a $^{64}$Zn beam at 330 MeV to bombard a $^{58}$Ni target. In this experiment, the fusion products were separated in flight through the newly commissioned recoil mass separator MARA and implanted into a double-sided silicon strip detector. The proton decay of the ground state of $^{117}$La was remeasured and found to be consistent with previous studies. In addition, we observed a new proton decay line, most likely from the ground state of $^{116}$La.
