You mention the Nucleonica decay engine - but why don't just use this?. The people at Nucleonica (www.nucleonica.com) have solved all the problems you mention.

this is all described in the Nucleonica wiki article at... http://www.nucleonica.net/wiki/index.php/Help:Gamma_Spectrum_Generator

..but if the 18 keV electrons are absorbed within the 2 mm pellet so also will all lower energies.

You can check the results with the Decay Engine in Nucleonica (www.nucleonica.net). This is a full web-based application for such calculations. For more information see ... http://www.nucleonica.net/wiki/index.php/Help:Decay_Engine

The ß- energy from H-3 decay is 18.51 keV. Using the Range and Stopping Power module in Nucleonica (www.nucleonica.net, free access but registration required) with the target solid hydrogen (density 0.08 g/cm2), the range is approximately 40 µm. So all the betas will be absorbed.

Take another look at http://www.nucleonica.net/wiki/index.php/Unbound_state. The definition has been updated to include an explanation including a diagram. Hope this is clearer now.

for a discussion of the resonance width see the http://www.nucleonica.net" glossary at... http://www.nucleonica.net/wiki/index.php/Category:Glossary This gives a relation between the resonance width and the half-life for a so-called unbound state. for a discussion on unbound states...

surprised nobody has mentioned Fundamentals of Nuclear Science and Engineering by J. Kenneth Shultis and R. E. Faw. Its an excellent textbook. Another great little book is Introduction to Nuclear Concepts for Engineers by R. M. Mayo.

Check out the Nucleonica nuclear science web portal at www.nucleonica.net. Access to the site is free but it requires registration. Lots of online web applications with technical documentation in the Nucleonica wiki.

but what about the therapeutic effects of radiation? here is a quote from the textbook Radioactivity, Radionuclides and Radiation (available online at...http://www.springer.com/new+%26+forthcoming+titles+%28default%29/book/978-3-540-21116-7) "Observations of the beneficial effects of radon...

Electron spallation will not work. Even with high energy protons it is a problem to produce enough neutrons. 1 GeV protons for example will produce only around 30 neutrons per proton in a heavy spallation target. This is why the laser fusion approach for neutron production is interesting. The...

We have been discussing something similar in the previous forum thread... see https://www.physicsforums.com/showthread.php?t=390161 (hybrid fusion fission reactor prospects) The accelerator driven systems have also been considered in Europe, but using a cyclotron rather than a linac - needs...

Yes. Fission reactors need to be critical. As soon as they go sub-critical, the reactor will switch off. Before this happens, new fuel must be intoduced into the system. Alternatively, one could use an external source of neutrons. Then one has a has a neutron driven sub-critical system. This is...
