The $\frac{1}{2}^+ \rightarrow \frac{1}{2}^+$ superallowed mixed mirror decay of $^{19}$Ne to $^{19}$F is excellently suited for high precision studies of the weak interaction. However, there is some disagreement on the value of the half-life. In a n

Laser spectroscopy of short-lived radium isotopes in a linear Paul trap has been performed. The isotope shifts of the $6d\,^2$D$_{3/2}\,$ - $7p\,^2$P$_{1/2}\,$ transition in $^{209-214}$Ra$^+$ were measured, which are sensitive to the short range par

On-line Excited-State Laser Spectroscopy of Trapped Short-Lived Ra$^+$ Ions

Autor: Versolato, O. O., Giri, G. S., Wansbeek, L. W., Berg, J. E. van den, van der Hoek, D. J., Jungmann, K., Kruithof, W. L., Onderwater, C. J. G., Sahoo, B. K., Santra, B., Shidling, P. D., Timmermans, R. G. E., Willmann, L., Wilschut, H. W.

As an important step towards an atomic parity violation experiment in one single trapped Ra$^+$ ion, laser spectroscopy experiments were performed with on-line produced short-lived $^{212,213,214}$Ra$^+$ ions. The isotope shift of the $6\,^2$D$_{3/2}

Production of short lived radioactive beams of radium

Autor: Shidling, P. D., Giri, G. S., van der Hoek, D. J., Jungmann, K., Kruithof, W., Onderwater, C. J. G., Sohani, M., Versolato, O. O., Willmann, L., Wilschut, H. W.

Short lived $^{212,213,214}$Ra isotopes have been produced at the TRI$\mu$P facility in inverse kinematics via the fusion-evaporation reaction $^{206}$Pb+$^{12}$C at 8 MeV/u. Isotopes are separated from other reaction products online using the TRI$\m
