  3. IS 529: Spins, Moments and Charge Radii Beyond 48Ca Proposal Objectives: 49..52Ca  First use of the new optical detection station with ions. release Tac≈ 100 ms Tb ≈3μs

  4. IS 529: Spins, Moments and Charge Radii Beyond 48Ca 52Ca with ≈ 300 ions/s after 4 hours

  5. IS 497: Laser Spectroscopy of Cadmium Isotopes: Probing the Nuclear Structure Between the Neutron 50 and 82 Shell Closures  Proposal Objectives: 100..130Cd In the process of reaching this a new wavelength range was opened up.

  6. Commissioning of the laser system 215 nm 430 nm 860 nm 35 mW output maintained over 5 hours

  7. IS 497: Laser Spectroscopy of Cadmium Isotopes: Probing the Nuclear Structure Between the Neutron 50 and 82 Shell Closures 130Cd # counts transition in Cd II: 5s 2S1/2 → 5p 2P3/2 @ 214 nm dn

  9. IS 484: Ground-state properties of K-isotopes from laser and β-NMR spectroscopy Proposal Objectives: 51K 

  10. I 88: β-NMR as a novel technique for biological applications Pressure-dependent β-decay asymmetry  Objective: Demonstrate online β-NMR in liquid samples . MgO single crystal Ionic liquid Beam transmission

  11. I 88: β-NMR as a novel technique for biological applications βNMR spectrum for 31Mg in ionic liquid EMIM-Ac

  12. IS 508: Collinear laser spectroscopy of manganese isotopes using optical pumping in ISCOOL Proposal Objectives: 57..66Mn 10.5 shifts of 18 taken. 51..64Mn measured including 58,60,62Mn isomers .  N=32

  13. IS 508: Collinear laser spectroscopy of manganese isotopes using optical pumping in ISCOOL

  14. Outlook for Ca Radioactive detection of Optically pumped ions after state selective Charge exchange (ROC) The theoretical possibilities: 1 ion/s of an even isotope over 5 shifts.

  15. Outlook for Cd Yields drop by 2 orders of magnitude per isotope beyond 100 or 130… The limit. But Laser system developed opens up many more possibilities in this region And beyond. Publications of spins moments and charge radii in preparation . -> See poster by D. T. Yordanov for more details.

  16. Outlook for K Publications: Spins and Moments (J Papugaet al.) in preparation. Charge radii (K. Kreimet al.) in preparation. See Poster by Jasna for details. Future prospects: With an intensity upgrade 52K comes into reach. Quadrupole moments may also shed light on the structural evolution in this region .

  17. Outlook for Bio - β-NMR Publications: Proof of concept results in preparation for publication. See talk by A. Gottberg. Future prospects: Enormous possibilities for both Biological and Solid State physics . but Will require a dedicated beamline and laser systems. Possibilities to develop polarized beams for an entire range of elements.

  18. Outlook for Mn Analysis underway by B. Cheal and C. Babcock. Realignment of ISCOOL during the shutdown will allow optical pumping in the cooler for this case and others. - 65, 66Mn are then easily reached.
