  The elastic scattering $^{12}$C(p,po) Excitation Function (EF) was measured
in the energy range Ep =16 - 19.5 MeV with resolution about 10 keV by means of
innovative approach - MSS - the Method of Spectra Superposition at the 14-angle
Magnetic Spectrograph (Apelsin) at beam with an energy spread of about 200 keV
from 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 agreement
with thresholds and levels data [2,9-12]. Measurements were done on the 12C
self-supporting target with thickness 13 mg/cm2 and an area of 1 cm2 in the
center 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 all
the ionic-optics on the 41-meter-long beam-pipe. Energy resolution of Apelsin
for protons is better than 5 keV along all focal plane, where particle-product
were detected by specially designed coordinate-sensitive gas mixture MWPC with
two particle counters in coincidence. The acquisition system was based on IBM
PC online with a fast CAMAC branch (custom designed at St-Petersburg PNPI) with
fast TDC modules and other fast electronics providing immediate selection and
accumulations of events from MWPCs. The NMR-monitor system stabilized
spectrographs magnetic field to 3ppm [1,9]. The EF of 12C (p,po) scattering has
many resonances that precisely correspond to g.s. and levels of well-known
product-nuclei. But 80 percent of anomalies did not have any explanation. A new
concept is proposed to explain all unrecognized anomalies. Two expressions
Writing I and Writing II proposed to explain the unknown peaks which
corresponds to population of A13 phase volume states. The results of the
proposed explanation look very promising (Fig. 13). Concept of the Combinative
Isobaric Resonances (CIRs) proposed
