INFLUENCE OF INITIAL REACCELERATION PHENOMENA BY STRONG SHOCK ON THE SUB FE FE RATIO/

Using the analytical model based on the influence of initial strong sh ock acceleration, the nux of the primary Fe nuclei and the sub Fe/Fe r atio were extrapolated to the sources and compared with the expected r esults. The source spectrum derived from the SSLB (steady-state leaky- box model) and from the Fe spectrum measured at the top of the atmosph ere, by balloon-borne plastic-emulsion chamber experiments, follows th e form similar to p(-2.19) where p is the momentum. Weak reacceleratio n also occurs due to strong shocks at a rate B = 0.410 cm(2) gm(-1) wh ere B is the inverse path length between shocks and is found to be con current with the expected result in the inter stellar medium based on the galactic escape length and on the projectile fragmentation cross s ections. The derived (Sc-Cr)/Fe flux ratios from the WELST (Wandel, Ei chler, Letaw, Silberberg, and Tsao) model at the sources without and w ith the reacceleration term have been compared with our and other rese archers results.
