Cu是一个有用的放射性同位素,它具有合适的半衰期(3.4小时)及便于测量的γ射线能量(0.283、0.373、0.511及1.185MeV)。关于
61
Cu衰变的γ射线谱,不同作者提供的纲图有若干分歧

,因此,制取纯
61
Cu,进行
61
Cu的衰变γ射线谱的测量,建立一个新的能级纲图是一项很有意义的工作

Cu produced by alpha particle bombordment of natural nickel target was separated from target and purified with anion exchanger. The method is as follows.
61
Cu is adsorpted on strong alkali anion exchanging column from 8
N
HC1 with a large amount of Ni passing through. 2
N
HC1 is then used to elute
61
Cu from the column. By checking of γ-spectrum and half-life the
61
Cu thus formed is proved pure enough for determination of its nuclear parameters. The method can also be applied to prepare medical radioisotope
62
Zn from 30MeV
a
particle bombarded Ni target. However
0.05N HC1 is used to elute
62
Zn.
