چکیده انگلیسی
Releases of short-lived species from ISOL targets are simulated with computer codes. Analytic solutions to the diffusion equation are compared with those obtained from a finite-difference code for radioactive isotope diffusion release from simple geometry targets. The Monte Carlo technique as a practical means for vapor transport system design is demonstrated by simulating the effusive-flow of neutral particles through complex target–vapor transport systems. Particle release curves involving decay losses in both diffusion and effusive-flow are computed; and a numerical procedure is proposed to measure the diffusion coefficients and the characteristic effusion times of rare isotopes in target–ion source systems.
