Precision mass measurements of radioactive nuclei at JYFLTRAP
نویسنده
چکیده
The Penning trap mass spectrometer JYFLTRAP was used to measure the atomic masses of radioactive nuclei with an uncertainty better than 10 keV. The atomic masses of the neutron-deficient nuclei around the N = Z line were measured to improve the understanding of the rp-process path and the SbSnTe cycle. Furthermore, the masses of the neutron-rich gallium (Z = 31) to palladium (Z = 46) nuclei have been measured. The physics impacts on the nuclear structure and the r-process paths are reviewed. A better understanding of the nuclear deformation is presented by studying the pairing energy around A = 100. PACS. 07.75.+h, 21.10.Dr, 27.50.+e, 27.60.+j

Preparing isomerically pure beams of short-lived nuclei at JYFLTRAP
A new procedure to prepare isomerically clean samples of ions with a mass resolving power of more than 1×10 has been developed at the JYFLTRAP tandem Penning trap system. The method utilises a dipolar rf-excitation of the ion motion with separated oscillatory fields in the precision trap. During a subsequent retransfer to the purification trap, the contaminants are rejected and as a consequence...

Masses of the radioactive isotopes Ga, Zn and Cu have been measured at the JYFLTRAP facility with a relative precision of better than 1.8× 10. A QEC value of (9181.07 ± 0.54) keV for the superallowed decay of Ga is obtained from the measured cyclotron frequency ratios of Ga—Zn, Ga—Ni and Zn—Ni ions. The resulting Ft-value supports the validity of the conserved vector current hypothesis (CVC). T...

متن کاملA Cooler Ion Trap for the TITAN On-line Trapping Facility at TRIUMF
We present simulations of electron and proton cooling of highly charged ions in a Penning trap, including the potentially detrimental effects of radiative, dielectronic, and three-body recombination in electron cooling. We show a preliminary design for a cooler trap accommodating both electron and proton cooling, which will be a component of the TITAN ion-trap facility under construction at TRI...
