General Comments:

2005As01: 236Am produced in 235U(6Li,5n) reaction at E=43-48 MeV; mass-separated with a resolution of M/ΔM≈800; implanted and transported to a measuring position with a short coaxial Ge detector (ORTEC LOAX) and a 35% n-type Ge detector (ORTEC GMX); Measured Eγ, Iγ, Iβ, γγ, γ-x ray coin, γ-x ray(t) coin, lifetimes. Also reported in 2004Sa05, 2002As08, 2002AsZX and 2000AsZY.

Growth and decay of 5760α of 236Pu in an Am fraction chemically separated from W target irradiated with 24-GeV protons was reported in 1987Ma21. The deduced T1/2 of 0.6 y 2 was ascribed in 1987Ma21 to a long-lived isomer of Am decaying by ε to 236Pu. The activity was followed for 15 y.
