A simultaneous analysis of two different 5 pi final states from pN annihilation at rest is used to study the decays of isoscalar 0/sup ++/ states into 4 pi /sup 0/. The data demand two scalar states, the f/sub 0/(1370) with m=1395+or-40 MeV/c/sup 2/, Gamma =275+or-55 MeV/c /sup 2/ and the f/sub 0/(1500) with mass and width compatible with previous findings. Apart from the dominant scalar intensity, the pi (1300) plays an important role in the 5 pi dynamics. We find a mass of m=1375+or-40 MeV/c/sup 2/ and a width of Gamma =268+or-50 MeV/c /sup 2/ with a dominant decay into rho pi . The ( pi pi )/sub s/ pi - decay of the pi (1300) is less than 15% of its rho pi decay. (33 refs)
