摘要:

We report the first measurement, at theXTU Tandem+LINACaccelerator of the Laboratori Nazionali di Legnaro, of the decay of the very neutron deficient nucleus117Lausing a 310 MeV58Nibeam on a64Zntarget; the117Lanucleus was populated via the (p, 4n) evaporation channel. The Recoil Mass Spectrometer (RMS) was used to selectM/q=117/30recoils that were implanted in a(40×40)&hthinsp;mm2Double Sided Silicon Strip Detector (DSSD) detector. The analysis has revealed that117Ladecays to116Bavia proton emission withEp=(783±6)keVandT1/2=(20±5)&hthinsp;ms.From this result deformation parameters of&bgr;2=0.3and&bgr;4=0.1have been deduced for the117Laground state which was assigned toJ&pgr;=3/2+.©2000 American Institute of Physics.
