The whole experimental procedure was similar as last year. To increase the yield of expected isotopes with intensive 12C beam, all of the irradiation have been done at night, and typical beam intensities varied between 0. 4-0.6 particleμA. Each irradiation lasted 4-6 h. The procedure of preparing展开更多
