测得异构体的半衰期为68(2)ns，并发现了新的衰变途径。这包括直接到基态转动带的高度禁忌射线跃迁，其阻值降低，可以与较重核素的阻值相比较。新的数据支持能级密度是决定禁忌跃迁速率的关键变量的解释。
The half-life of aisomer inEr has been measured to be 68(2) ns, and new decay pathways have been identified. These include highly-forbidden-ray transitions directly to the ground-state rotational band, with reduced hindrance values that can be compared with those found for heavier nuclides. The new data support the interpretation that the level density is a key variable in determining-forbidden transition rates.
