Takahashi's theory ... it seems to me that it predicts most known
CF phenomena:
1. No direct neutrons.
2. Surface reaction, since deuterium dissociates on entering the
lattice.
3. Takahashi predicts from quantum theory that if the TSC forms, it
will fuse 100%.
4. No momentum transfer problem, all energy is kinetic with the
alpha particles.
5. Alpha radiation.

The emission of barely detectable amounts of 23.8 MeV alphas from
thin foils or co-deposition experiments is not consistent with the
excess heat observed. Given that most fusion is said to occur, by
Takahasi's theory and many others, at the surface, and given that co-
deposted cathode surfaces are made up of nanometer scale particles,
there is not enough barrier to 13 MeV alpha particles in typical
cathodes to suppress their detection enough to account for the low
count densities. To make a rough approximation based on copper,
particle attenuation in Pd at 13 MeV should be less than 0.3 MeV/mg/
cm^2. The density of Pd is 12 g/cm^3. A 100 micron foil weighs 12 g/
cm^3 * (100x10^-6 cm) = 0.0012 g/cm^2 = 1.2 mg/cm^2. Attenuation in
a 100 micron thick Pd foil, a 1.2 mg/cm foil, would only be on the
order of (0.3 MeV/mg/cm^2) * (1.2 mg/cm) = 360 keV. Water would of
course attenuate further, but direct CR-39 contact, such as that used
in the SPAWAR experiments, even with the added attenuation of an
intervening 6 micron plastic film, should not significantly reduce
the count of the 32 MeV alphas, only their apparent energies. The
excess heat, observed in surface hot spots, by SPAWAR and various
others, demand a significant particle count.
