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.

Abstract: | 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. |
