Description
Recent analysis of nuclear binding energies and nuclear excitations of the
broad scope of nuclei allowed a conclusion that there exists a discreteness
in both values with stable mass/energy intervals coinciding or rationally
connected with charge mass splitting of the nucleon $\delta m_N$=1293.3~keV and
the lepton $m_e$=511~keV. For example, periods $\delta m_N$/8=161~keV and
$m_e$/3=171~keV were observed in excitations of near-magic nuclei
$^{odd}$Sb (Z=51, numbers of the period n=1,2,3,4,5,6) and
$^{101,133}$Sn (Z=50, N=51,83, n=1,5,8).
In neighbour nuclei $^{116,117,118}$Sn and $^{113}$In phonon-like excitations
with values close to $\delta m_N$ and $2m_e$=$\varepsilon_o$ were found in
first excitations, as well as many stable intervals D=511~keV, 1533~keV and
2045~keV ($m_e$, 3$m_e$, 4$m_e$) - in all 183 levels of $^{113}$In.
Similar groupings of excitations at $\delta_N$ and $\varepsilon_o$ was reported
in sum distribution for all nuclei [1].
Such tuning effect in nuclear data could be considered together with the empirical
tuning effect in particle masses which consisted in rational relations between
mass-values of the muon, pion, nucleon and standard (in NRCQM) estimations of
the constituent quark masses $m_{\rho}$/2 and $m_{\Xi}$/3 [2.3].
We use evaluation by CODATA [4] of the ratio 1838.6836605(11) between masses of
the neutron and electron for determination of the shift of the neutron mass
$\delta m_n$=161.65(6) keV relative to the integer number of the electron rest
mass, namely 115$\delta$ - $m_e$ where the parameter $\delta$=16$m_e$
was introduced in 70-ties as a common period in particle masses (close to double
value of the pion $\beta$-decay energy [3,5]).
The value $\delta m_n$=161.65(6) keV forms the ratio 8$\times$1.001(1) with the
nucleon mass difference $\delta m_N$. This exact relation
could be considered as important confirmation of the common tuning effect in
particle masses and nuclear excitations (was considered in [3]). \\
