 *     block data of yields from Mewe paper
 *     vyield( nelem, nstage, nshell, nelec )
 *     nelem is element number, 6 for carbon
 *     nstage is stage of ionization, 1 for atom
 *     nshell is shell number in dima notation
 *     nelec is fraction that yield that number of electrons
 **    nyield is number of electrons at most
