## Investigation of the 241Am(n,2n)240Am cross section

The $^{241}\mathrm{Am}(n,2n)^{240}\mathrm{Am}$ reaction cross section has been measured at four energies, 10.0, 10.4, 10.8, and 17.1 MeV, by means of the activation technique, relative to the $^{27}\mathrm{Al}(n,\ensuremath{\alpha})^{24}\mathrm{Na}$ reaction reference cross section. Quasi-monoenergetic neutron beams were produced via the $^{2}\mathrm{H}(d,n)^{3}\mathrm{He}$ and the $^{3}\mathrm{H}(d,n)^{4}\mathrm{He}$ reactions at the 5.5 MV Tandem T11/25 accelerator laboratory of NCSR Demokritos''. The high purity $^{241}\mathrm{Am}$ targets were provided by JRC-IRMM, Geel, Belgium. The induced $\ensuremath{\gamma}$-ray activity of $^{240}\mathrm{Am}$ was measured with high-resolution high-purity germanium (HPGe) detectors. Auxiliary Monte Carlo simulations were performed with the mcnp code. The present results are in agreement with data obtained earlier and predictions obtained with the empire code.

## X-ray breakthrough 'opens door' to controlled nuclear fusion

Scientists have for the first time been able to monitor the flow of energy during fast ignition, a process that it hoped to be capable of creating controlled nuclear fusion
Mikko Hakala's curator insight,

X-ray imaging helps develop fast ignition methods in nuclear fusion. The challenge is to follow where the energy of the high-intensity laser goes in the 2nd step of the ignition, the target area being the densest region of the compressed fuel.

To monitor this, Cu tracers are used, which are hit by fast electrons generated by the intensive laser. The resulting X-ray fluorescence radiation from Cu is then used for advanced spatial imaging of the energy deposition.

## One-neutron removal from 29Ne: Defining the lower limits of the island of inversion

Background: Very neutron-rich isotopes, including $^{30\ensuremath{-}32}\mathrm{Ne}$, in the vicinity of $N=20$ are known to exhibit ground states dominated by $fp$-shell intruder configurations: the island of inversion.'' Systematics for the Ne-isotopic chain suggest that such configurations may be in strong competition with normal shell-model configurations in the ground state of $^{29}\mathrm{Ne}$.

## Angle-integrated measurements of the 26Al (d, n)27Si reaction cross section: a probe of spectroscopic factors and astrophysical resonance strengths

Theo J. Mertzimekis's insight:

Measurements of angle-integrated cross sections to discrete states in 27Si have been performed studying the 26Al (d, n) reaction in inverse kinematics by tagging states by their characteristic γ -decays using the GRETINA array. Transfer reaction theory has been applied to derive spectroscopic factors for strong single-particle states below the proton threshold, and astrophysical resonances in the 26Al (p,γ) 27Si reaction. Comparisons are made between predictions of the shell model and known characteristics of the resonances. Overall very good agreement is obtained, indicating this method can be used to make estimates of resonance strengths for key reactions currently largely unconstrained by experiment.

## New chemistry revives elementary question

The periodic table is a public symbol of chemistry. But as it grows larger, we must stress that science is not just about producing lists, says Philip Ball.
Theo J. Mertzimekis's insight:

I would rather see a "lemmium" that a "levium" in the periodic table :-)
