A new approach for deducing rms proton radii from charge-changing reactions of neutron-rich nuclei and the reaction-target dependence.

We report the charge-changing cross sections (σ) of 24 p-shell nuclides on both hydrogen and carbon at about 900A MeV, of which Li, Be, B, N and O on hydrogen and Li on carbon are for the first time. Benefiting from the data set, we found a new and robust relationship between the scaling factor of the Glauber model calculations and the separation energies of the nuclei of interest on both targets. This allows us to deduce proton radii (R) for the first time from the cross sections on hydrogen.

One-day session LINAC-based stereotactic radiosurgery of posterior uveal melanoma.

Purpose: LINAC-based stereotactic radiosurgery (SRS) of posterior uveal melanoma is a conservative method to treat uveal melanoma.

Methods: This was a retrospective clinic-based study of patients with posterior uveal melanoma in stage T2/T3 who underwent 1-day session SRS at LINAC accelerator or SRS plus combined methods from 2001 to 2008.

Results: Thirty-nine patients with posterior uveal melanoma were treated with SRS (age 25-80 years, median 54 years).
