The elastic scattering $^{12}$C(p,po) Excitation Function (EF) was measuredin the energy range Ep =16 - 19.5 MeV with resolution about 10 keV by means ofinnovative approach - MSS - the Method of Spectra Superposition at the 14-angleMagnetic Spectrograph (Apelsin) at beam with an energy spread of about 200 keVfrom U-150 cyclotron of INP Ulugbek (Tashkent) of Science Academy of Uzbekistan[1-8]. The obtained EF has a reach structure of anomalies in precise agreementwith thresholds and levels data [2,9-12]. Measurements were done on the 12Cself-supporting target with thickness 13 mg/cm2 and an area of 1 cm2 in thecenter of Apelsin. The 20-step Energy Moderator controlled the proton energy,providing a 3.5 MeV wide Ep interval with no readjustment of cyclotron and allthe ionic-optics on the 41-meter-long beam-pipe. Energy resolution of Apelsinfor protons is better than 5 keV along all focal plane, where particle-productwere detected by specially designed coordinate-sensitive gas mixture MWPC withtwo particle counters in coincidence. The acquisition system was based on IBMPC online with a fast CAMAC branch (custom designed at St-Petersburg PNPI) withfast TDC modules and other fast electronics providing immediate selection andaccumulations of events from MWPCs. The NMR-monitor system stabilizedspectrographs magnetic field to 3ppm [1,9]. The EF of 12C (p,po) scattering hasmany resonances that precisely correspond to g.s. and levels of well-knownproduct-nuclei. But 80 percent of anomalies did not have any explanation. A newconcept is proposed to explain all unrecognized anomalies. Two expressionsWriting I and Writing II proposed to explain the unknown peaks whichcorresponds to population of A13 phase volume states. The results of theproposed explanation look very promising (Fig. 13). Concept of the CombinativeIsobaric Resonances (CIRs) proposed
