First Direct Observations of Gear-Changing In A Collider
E. Nissen, A. Källberg, A. Simonsson
In this work we perform the first ever demonstration of gear-changing in a real world collider. Gear-changing refers to a collision scheme where each ring of a collider stores a di…
Radiative lifetimes of the bound excited states of
K. C. Chartkunchand, M. KamiÅska, E. K. Anderson +20
The intrinsic radiative lifetimes of the and bound excited states in the platinum anion have be…
Lifetimes of excited states in P-, As- and Sb-
J. Karls, M. Björkhage, M. Blom +12
Radiative lifetimes of three elements of the nitrogen group have been experimentally investigated at the Double ElectroStatic Ion Ring Experiment (DESIREE) facility at Stockholm Un…
Rotationally cold OH ions in the cryogenic electrostatic ion-beam storage ring DESIREE
H. T. Schmidt, G. Eklund, K. C. Chartkunchand +14
We apply near-threshold laser photodetachment to characterize the rotational quantum level distribution of OH ions stored in the cryogenic ion-beam storage ring, DESIREE, at St…
Precision measurements on Si-
J. Karls, H. Cederquist, N. D. Gibson +12
High-precision measurements of the electron affinities (EA) of the three stable isotopes of silicon, Si, Si and Si, have been performed at the cryogenic electr…
The lifetime of the bound excited level in Ni
M. KamiÅska, V. T. Davis, O. M. Hole +16
The intrinsic lifetime of the upper level in the bound-bound 3d4s D 3d4s D radiative transition in Ni was measured to be 1…
