Simplicity is the key to a good sig… especially when you can easily add your concept to an existing sig without getting overly complicated. Excessive verticality is a no-go.
Simplest of all would be the actual text, something along the lines of
p +11B→3x4He + 8.7MeV
… or somesuch…
…
… …
… … … but since I’m already here you can try starting with this as a base and work it out from there…
PNP NPNP
P + NPNPN –> PNPN –> PNPN + PNPN + PNPN + 8.7 Mev
NPN NPNP
