Invariant-mass spectroscopy of 10B, 11C, 14F, 16F, and 18Na

The invariant-mass method is used to study the structure of a number of light proton-rich isotopes utilizing fast beams. Reactions where the projectile picks up a proton have been used to study d-wave resonances in 14F, 16F, and 18Na. While the 16F and 18Na results are consistent with previous studi...

Description
Summary:The invariant-mass method is used to study the structure of a number of light proton-rich isotopes utilizing fast beams. Reactions where the projectile picks up a proton have been used to study d-wave resonances in 14F, 16F, and 18Na. While the 16F and 18Na results are consistent with previous studies, the 14F results are not consistent with the only previous work. Here, we have tentatively identified the 4+ member of a rotational band in 10B, which is the analog of well-known states with strong α-cluster structure in 10Be and 10C. Finally, spin and parities of newly observed states in 11C which decay sequentially into three-body exit channels have been determined or restricted.
