Two-proton relative momentum distributions from the break-up channels 23Al→p+p+21Na and 22Mg→p+p+20Ne at an energy of 60-70 A MeV have been measured together with two-proton opening angles at the projectile fragment separator beamline (RIPs) in the RIKEN Ring Cyclotron Facility. The results demonstrate the existence of diproton emission component from single-step 2He for highly excited 23Al and 22Mg.

PURPOsE: To determine the changes in the retinal pigment epithelium(retinal pigment epithelium) and secondary changes in the choroid and fovea after indocyanine green (ICG) staining of the internal limiting lamina during surgery for an idiopathic macular hole (MH). DEsIGN: Observational case series. METHODs: The medical charts of 31 patients who underwent MH surgical procedures with internal limiting lamina staining and peeling were reviewed. The eyes were examined by optical coherence tomography, scanning laser ophthalmoscopy, fluorescein, and ICG angiography. REsULTs: In three cases that experienced retinal pigment epithelium changes, there was foveal thinning and choriocapillary atrophy in the area of the previous MH. The visual acuity was markedly worse, and the retina was markedly thinner in these three cases than in the other cases without retinal pigment epitheliumchanges (P=.003, P=.009, respectively). CONCLUsION: The use of ICG dye with illumination may increase the risk of retinal pigment epithelium damage and secondary choroidal and foveal morphologic changes.

The lifetime of the first excited 2+ state in 18C was measured using an upgraded recoil shadow method to determine the electric quadrupole transition. The measured mean lifetime is 18.9±0.9(stat)±4.4(syst)ps,which corresponds to a B(E2; 2+1→0+gs) value of (4.3± 0.2±1.0) e2fm4,or about 1.5 Weisskopf units. The mean lifetime of the first 2+ state in 16C was remeasured to be about 18 ps,about four times shorter than the value reported previously. This discrepancy was explained by incorporating the γ-ray angular distribution measured in this work into the previous measurement. The observed transition strengths in 16,18C are hindered compared to the empirical transition strengths,indicating that the anomalous hindrance observed in 16C persists in 18C.

Introduction Neutron-rich fluorine isotopes are interesting in their features. A recent discovery revealed that the stability of neutron-rich isotopes remarkably changes between oxygen and fluorine isotopes [1]. The fluorine isotopes are extended up to F with N=22 beyond the magic number of N=20 while the heaviest oxygen isotope is O with N=16. This feature may indicate that a strong attraction works between a valence proton on the d shell and valence neutrons in fluorine isotopes.
