²⁰⁸Hg β衰变新γ射线的初步观察

摘要: 利用８．４ＭｅＶ／ｕ的１８Ｏ束轰击天然铅靶，分离出汞元素产物，并以此研究２０８Ｈｇβ衰变的新γ射线．除已报道的γ射线以外，观察到对应于２０８Ｔｌ已知能级间跃迁的９条新γ射线.The Hg products produced in the bombardment of natural lead targets by 18 O beam of 8.4 MeV/u were separated by means of an off line gas thermochromategraphic device. The coincident gamma spectra and time successive single γ ray spectra were measured. Except the already known γ rays, nine new γ rays assigned to the transitions between the known levels of 208 Tl were observed.
