I don't know about the "similar result at SRI." Citation, please.
See experiment HH from SRI Technical Report TR-107843-V1, by McKubre et al., starting on p. 3-26. Here is part of the relevant discussion, which is necessarily abridged:
For comparison with the M4 experiment: these HH samples are associated with about a tenth of the excess power of the M4 power levels, over a comparable period of time, and with helium measurements that are in the ppbv versus ppm and which are more or less indistinguishable from null helium measurements. Similarly to Miles, the cathode material was Pd:Ce:Sm, with samarium included where it was not reported in Miles (if I recall). I do not have a strong handle on the HH experiments (or the M-series ones), so I might be reading something incorrectly into this. But at some point I recall making a connection to the Pd-Ce/D experiments that Miles reported on.
