Two To Two Reactions - data provided by Dr. Alexander Parkhomov

Conceived by R. W. Greenyer and coded by P. W. Power for the Martin Fleischmann Memorial Project

Version 5.0, Sep 28, 2019

This program enables SQL commands to query the TwoToTwo (2-2) tables originally created from Dr Parkhomov's spreadsheets.

To make full use of this and the other database tables, a good grasp of SQL is essential.

But note that it and Fission and Fusion is each dedicated to querying only one of two tables.

The "universal" program All Tables can accept full SQL commands that query any of the 12 "Parkhomov" tables, together with the "ElementProperties", "Nuclides", "RadioNuclides" and "Atomic Radii" tables as well.

You may indicate which of the three neutrino conditions to include: "left" and/or "none" and/or "right". The default condition is include all three.

In all the above tables, except the Periodic, each atom, in either the input or the output, as well as its 'A' and 'Z' numbers now also has a 'nBorF' ('nuclear Boson or Fermion') and a 'aBorF' ('atomic Boson or Fermion') parameter associated with it.

An atom's nucleus is considered a Boson ('b') if its A number is even; if odd a Fermion ('f'). The atom itself is considered a Boson ('b') if its number of neutrons (A - Z) is even; if odd a Fermion ('f').

These parameters can be used either passively, by observing the distributions of 'b' and 'f' in inputs and/or outputs, and/or actively, by selecting 'b only', 'f only' or 'either' in the boxes below.

NB: To avoid unnecessary duplication in all TwoToTwo tables, two rules independently apply: A1 <= A2 and A3 <= A4. These rules also apply implicitly in that, if the input side of the Core Query only involves E1 and E2, only rows whose associated mass numbers obey A1 <= A2 will appear in the results. Similarly with E3 and E4 on the output side, only rows whose associated mass numbers obey A3 <= A4 will appear in the results.

Input used for this run on 28-Feb-2026 08:22:58 (NZT):

Full SQL Query: "select * from TwoToTwoAll where E1 in ('Zr', 'Nb') and E2 in ('Zr', 'Nb') order by MeV desc limit 100"

44 rows were found.
