Single-neutron knockout reactions: Application to the spectroscopy of C

Two-nucleon knockout spectroscopy at the limits of nuclear stability.

Sudden single-nucleon removal reactions from fast radioactive beams are now key to studies of the structure of rare isotopes. The sensitivity of the heavy residue's parallel momentum distribution to the orbital angular momentum of the removed nucleon is a crucial feature with a high spectroscopic value. Two-nucleon removal reactions provide experimental reach toward the rarest nuclear species. ...

Spectroscopy of 13 , 14 B via the one - neutron knockout reaction

The single-nucleon knockout reactions Be(B,B1g)X and Au(B,B1g)X , at an incident energy of 60 MeV per nucleon, have been used to probe the structure of B and of the core fragment B. A dominant 2s configuration is deduced for the neutron in the ground state of B. The longitudinal momentum distribution for this state is consistent with ‘‘neutron halo’’ structure. Spin assignments for B excited st...

Modification of 10 cGy neutron or gamma-rays induced chromosomal damages by hyperthermia: an in vitro study

Background: To evaluate the effects of hyperthermia (HT) on the frequency of chromosomal aberrations induced by a low dose of neutron or γ-rays in human peripheral blood lymphocytes. Materials and Methods: Blood samples were exposed to HT (41.5°C for 30 and 60min, 43°C for 15 and 30min), 10 cGy neutron or γ-rays, HT + neutron/γ, and neutron/γ + HT. After standard cell culture, harvestin...
