Abstract

The concept of
pseudo-mirror nuclei is based on NπNν scheme introduced
as an extension of NpNnscheme. The NπNν scheme
tells us that if two nuclei from different mass region have equal number of
integrated n-p interaction than the experimental observables E(2+), E(4+)/E(2+)
and B(E2; 2+
→ 0+) are expected to be almost equal,
therefore equal number of n-p interaction build similar level schemes up to
certain spin quantum numbers. Pseudo-mirror nuclei have been introduced for the
first time in the mass regions A ~ 100 and A ~ 130 for Mo, Zr, Nd and Ce
nuclei.  Later, a systematic work carried
out over a broad region of Segre chart showed
that not only the excitation energies but also related B(E2) values of excited
states in Pseudo-mirror nuclei (PMN) are in good agreement. In the present
work, we present new pseudo-mirror nuclei in the mass region A ~ 170 and A ~
200 for the first time.
