We have successfully performed in-beam gamma-ray spectroscopy using the isomer-scope technique to study excited-state structure of neutron-rich heavy-actinide nuclei. The neutron-rich heavy-actinide nuclei were produced in the multinucleon-transfer reactions with a Cm target and O projectiles accelerated with the JAEA tandem accelerator. Projectile-like scattered particles were detected with Si E-E telescopes placed at the backward angle, and target-like scattered particles of isomers were caught by an annular aluminum plate placed at about 60-mm downstream from the target. Four Ge detectors and 4 LaBr detectors were placed at the periphery of the aluminum plate, and detected gamma rays from the isomers. Gamma rays emitted from the actinide isomers were successfully observed with a good sensitivity owing to the tungsten shield placed between the target and the detectors.

Solar cells for power generation can be used as a high-energy heavy-ion detector because it has diode characteristics. To utilize the solar cells for fission-fragment measurements, we have investigated the response (energy resolution and pulse height defect) of a solar cell to heavy ions of various nuclides with several different energies.
