GRETINA Explores N=40 Structure
The goal of this week’s experiment was to determine the single-particle structure of neutron-rich N=40 nuclei. In this region, a reduction of the N=40 harmonic oscillator shell gap leads to a sudden increase in collectivity in the Fe and Cr … Continue reading

NSCL TRIPLEX Plunger’s Debut with GRETINA
This week, experiment 11013 was performed with the TRIPLEX plunger device mounted in the target position of the S800 spectrograph. Gamma rays emitted from nuclei in flight were measured by GRETINA. Excited-state lifetimes were measured for a range of nuclei … Continue reading

Experiment 11036 – GRETINA
Experiment 11036 ran this week beginning Tuesday morning in the S3 vault. The experiment sought to explore a central “bubble” thought to exist in the isotope 34Si. The nuclear force works on very short scales and is extremely strong. Thus, … Continue reading

GRETINA’s First Experiment at NSCL
In GRETINA’s first experiment at NSCL, which is running this week, the aim is to reduce the effect of the uncertainty in the 57Cu(p,γ)58Zn stellar reaction in the calculation of the light-curve emitted in X-ray bursts. GRETINA is being used … Continue reading

GRETINA Takes Shape
Progress continues to be made in setting up GRETINA in the S3 vault. The second hemisphere was installed and both hemispheres’ frames were aligned in front of the S800 spectrograph. The GRETINA data acquisition system now is up and running, … Continue reading

S3 Vault Ready for GRETINA
The S3 vault has been emptied slowly during the past few weeks, but it will not stay that way for long. Late in 2011, the roof beams were removed so that a crane could lift the scattering chamber up three … Continue reading
