Entangled two photon absorption cross section on the 808 nm region for the common dyes Zinc tetraphenylporphyrin and Rhodamine B
Juan. P. Villabona-Monsalve, Omar Calderón-Losada, Mayerlin Nuñez Portela +1
We report the measurement of the entangled two photon absorption cross section, , at 808 nm on organic chromophores in solution in a low photon flux regime. We performed measu…
A gas cell for stopping, storing and polarizing radioactive particles
A. Sytema, J. E. van den Berg, O. Böll +14
A radioactive beam of 20Na is stopped in a gas cell filled with Ne gas. The stopped particles are polarized by optical pumping. The degree of polarization that can be achieved is s…
Measurement of the branching ratio for beta-delayed alpha decay of 16N
J. Refsgaard, O. S. Kirsebom, E. A. Dijck +10
While the 12C(a,g)16O reaction plays a central role in nuclear astrophysics, the cross section at energies relevant to hydrostatic helium burning is too small to be directly measur…
Lifetime measurement of the 5dD state in Ba
Amita Mohanty, Elwin A. Dijck, Mayerlin Nuñez Portela +5
The lifetime of the metastable 5dD state has been measured for a single trapped Ba ion in a Paul trap in Ultra High Vacuum (UHV) in the 10 mbar pressure ran…
Determination of transition frequencies in a single Ba ion
E. A. Dijck, M. Nuñez Portela, A. T. Grier +4
Transition frequencies between low-lying energy levels in a single trapped Ba ion have been measured with laser spectroscopy referenced to an optical frequency comb.…
First Test of Lorentz Invariance in the Weak Decay of Polarized Nuclei
S. E. Müller, E. A. Dijck, H. Bekker +17
A new test of Lorentz invariance in the weak interactions has been made by searching for variations in the decay rate of spin-polarized 20Na nuclei. This test is unique to Gamow-Te…
Isotope Shifts of the D - P Transition in Trapped Short-Lived Ra
G. S. Giri, O. O. Versolato, J. E. van den Berg +13
Laser spectroscopy of short-lived radium isotopes in a linear Paul trap has been performed. The isotope shifts of the D - P transition in $^{209…
