Observation of 100Sn

Abstract Using a 112 Sn beam delivered by the GANIL cyclotrons in conjunction with the high acceptance device SISSI, proton-rich nuclei in the region of A=100 have been produced and subsequently analysed by the LISE3 spectrometer. As a result the doubly magic nucleus 100 Sn was identified with 11 events recorded during 44 hours.
