The extraction of ²¹¹At into ketones out of 1–3 M nitric acid shows better extraction than other solvents, with DFT calculations indicating stronger binding between the carbonyl oxygen of the ketone and the At metal center.

Isoscaling parameters α and β have been explored as a function of breakup angle in binary excited projectile-like fragment decays produced in collisions of 70 Zn + 70 Zn and 64 Zn + 64 Zn at 35 MeV per nucleon. In this analysis, focus was placed on isoscaling the second heaviest fragment with 4 ≤ ZL ≤ 8 emitted from the excited projectile-like fragment in events that contained a heavy fragment with ZH ≥ 12. The breakup orientation θprox was defined as the angle between the heavy and light fragments' center of mass velocity and the fragment pairs' relative velocity. Breakups between 0 • < θprox ≤ 80 • have been shown to be dominated by dynamical contributions, while break-up angles of θprox > 100 • are predominantly statistical. Historically, isoscaling has often been understood and applied in a statistical context, assuming that the fragments are produced after statistical equilibrium is achieved. Studying isoscaling parameters as a function of θprox reveals the sensitivity of α and β to the mechanism of fragment production.
